- Ensure that both sides are passed the appropriate companion data to
preserve spacers when syncing
- Remove companion handling in codepaths related to range folding, since
this isn't supported in the side-by-side diff
- Move handling of buffer folding into the block map

TODO:
- [x] diagnose and fix issue that causes balancing blocks not to render
properly when they are adjacent to spacers (e.g. merge conflict buttons)
- [x] clear balancing blocks when clearing companion
- [x] additional tests: interaction between spacers and balancing

The side-by-side diff heavily relies on a primitive from `buffer_diff`
that converts a point on one side of the diff to a range of points on
the other side. The way this primitive is set up on main is pretty
naive--every time we call `points_to_base_text_points` (or
`base_text_points_to_points`), we need to iterate over all hunks in the
diff. That's particularly bad for the case of constructing a new
side-by-side diff starting from a multibuffer, because we call those
APIs once per excerpt, and the number of excerpts is ~equal to the
number of hunks.
This PR changes the point translation APIs exposed by `buffer_diff` to
make it easier to use them efficiently in `editor`. The new shape is a
pair of functions that return a patch that can be used to translate from
the main buffer to the base text or vice versa. When syncing edits
through the block map that touch several excerpts for the same buffer,
we can reuse this patch for excerpts after the first--so when building a
new side-by-side diff, we'll iterate over each hunk just once.
The shape of the new APIs also sets us up to scale down to cases like
editing on the right-hand side of the diff: we can pass in a point range
and give them permission to return an approximate patch that's only
guaranteed to give the correct results when used with points in that
range. For edits that only affect one excerpt, and given how the project
diff is set up, that should allow us to skip iterating over most of the
hunks in a buffer.

The logic in `anchor_at_offset` and `to_offset` seems inverted when
checking character boundaries. `assert_char_boundary` returns `true`
when the offset IS valid, but the code was adjusting offsets when the
function returned `true` (valid) instead of `false` (invalid).

This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.
Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:
- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.
In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.
The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.
Release Notes:

As discussed in the first responders meeting. We have collected a lot of
backtraces from these, but it's not quite clear yet what causes this.
Removing these should ideally make things a bit more stable even if we
may run into panics later one when the faulty anchor is used still.

Closes https://github.com/zed-industries/zed/issues/38453
Current `Buffer` API only allows getting buffer text with `\n` line
breaks — even if the `\r\n` was used in the original file's text.
This it not correct in certain cases like LSP formatting, where language
servers need to have original document context for e.g. formatting
purposes.
Added new `Buffer` API, replaced all buffer LSP registration places with
the new one and added more tests.

Closes#5294
This PR adds a line ending indicator to the status bar, hidden by
default as discussed in
https://github.com/zed-industries/zed/issues/5294.
### Changes
- 8b063a22d8700bed9c93989b9e0f6a064b2e86cf add the indicator and
`status_bar.line_endings_button` setting.
- ~~9926237b709dd4e25ce58d558fd385d63b405f3b changes
`status_bar.line_endings_button` from a boolean to an enum:~~
<details> <summary> show details </summary>
- `always` Always show line endings indicator.
- `non_native` Indicate when line endings do not match the current
platform.
- `lf_only` Indicate when using unix-style (LF) line endings only.
- `crlf_only` Indicate when using windows-style (CRLF) line endings
only.
- `never` Do not show line endings indicator.
I know this many options might be overdoing it, but I was torn between
the pleasant default of `non_native` and the simplicity of `lf_only` /
`crlf_only`.
My thinking was if one is developing on a project which exclusively uses
one line-ending style or the other, it would be nice to be able to
configure no-indicator-in-the-happy-case behavior regardless of the
platform zed is running on. But I'm not really familiar with any
projects that use exclusively CRLF line endings in practice. Is this a
scenario worth supporting or just something I dreamed up?
</details>
- 01174191e4cf337069e7a31b0f0432ae94c52515 rename the action context for
`line ending: Toggle` -> `line ending selector: Toggle`.
When running the action in the command palette with the old name I felt
surprised to be greeted with an additional menu, with the new name it
feels more predictable (plus now it matches
`language_selector::Toggle`!)
### Future work
Hidden status bar items still get padding, creating inconsistent spacing
(and it kind of stands out where I placed the line-endings button):
<img alt="the gap after the indicator is larger than for other buttons"
src="https://github.com/user-attachments/assets/24a346d4-3ff6-4f7f-bd87-64d453c2441a"
/>
I started a new follow-up PR to address that:
https://github.com/zed-industries/zed/pull/39992
Release Notes:
- Added line ending indicator to the status bar (disabled by default;
enabled by setting `status_bar.line_endings_button` to `true`)
Reduces peak stack usage in these functions and should generally be a
bit performant.

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

This allows you to write `buffer_snapshot.debug(ranges, value)` and it
will be displayed in the buffer (or multibuffer!) until that callsite
runs again. `ranges` can be any position (`usize`, `Anchor`, etc), any
range, or a slice or vec of those. `value` just needs a `Debug` impl.
These are stored in a mutable global for convenience, and this is only
available in debug builds.
For example, using this to visualize the captures of the brackets

Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.
## Changes
- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.
## Benefits
- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.
Follows Rust guidelines; run `./script/clippy` for verification.
- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

In vim and zed (vim and helix modes) typing "tx" will jump before the
next `x`, but typing it again won't do anything. But in helix the cursor
just jumps before the `x` after that. I added that in helix mode.
This also solves another small issue where the selection doesn't include
the first `x` after typing "fx" twice. And similarly after typing "Fx"
or "Tx" the selection should include the character that the motion
startet on.
Release Notes:
- helix: Fixed inconsistencies in the "f" and "t" motions
This is a bit of a readability improvement IMHO; I often find myself
confused when dealing when dimension pairs, as there's no easy way to
jump to the implementation of a dimension for tuples to remind myself
for the n-th time how exactly that impl works. Now it should be possible
to jump directly to that impl.
Another bonus is that Dimension supports 3-ary tuples as well - by using
a () as a default value of a 3rd dimension.

C projects with `"` as "brackets" that autoclose, may invoke panics when
edited at the end of the file.
With a single selection-caret (`ˇ`), at the end of the file,
```c
ifndef BAR_H
#define BAR_H
#include <stdbool.h>
int fn_branch(bool do_branch1, bool do_branch2);
#endif // BAR_H
#include"ˇ"
```
gets an LSP response from clangd
```jsonc
{
"filterText": "AGL/",
"insertText": "AGL/",
"insertTextFormat": 1,
"kind": 17,
"label": " AGL/",
"labelDetails": {},
"score": 0.78725427389144897,
"sortText": "40b67681AGL/",
"textEdit": {
"newText": "AGL/",
"range": { "end": { "character": 11, "line": 8 }, "start": { "character": 10, "line": 8 } }
}
}
```
which replaces `"` after the caret (character/column 11, 0-indexed).
This is reasonable, as regular follow-up (proposed in further
completions), is a suffix + a closing `"`:
<img width="842" height="259" alt="image"
src="https://github.com/user-attachments/assets/ea56f621-7008-4ce2-99ba-87344ddf33d2"
/>
Yet when Zed handles user input of `"`, it panics due to multiple
reasons:
* after applying any snippet text edit, Zed did a selection change:
https://github.com/zed-industries/zed/blob/55379876301bd4dcfe054a146b66288d2e60a523/crates/editor/src/editor.rs#L9539-L9545
which caused eventual autoclose region invalidation:
https://github.com/zed-industries/zed/blob/55379876301bd4dcfe054a146b66288d2e60a523/crates/editor/src/editor.rs#L2970
This covers all cases that insert the `include""` text.
* after applying any user input and "plain" text edit, Zed did not
invalidate any autoclose regions at all, relying on the "bracket" (which
includes `"`) autoclose logic to rule edge cases out
* bracket autoclose logic detects previous `"` and considers the new
user input as a valid closure, hence no autoclose region needed.
But there is an autoclose bracket data after the plaintext completion
insertion (`AGL/`) really, and it's not invalidated after `"` handling
* in addition to that, `Anchor::is_valid` method in `text` panicked, and
required `fn try_fragment_id_for_anchor` to handle "pointing at odd,
after the end of the file, offset" cases as `false`
A test reproducing the feedback and 2 fixes added: proper, autoclose
region invalidation call which required the invalidation logic tweaked a
bit, and "superficial", "do not apply bad selections that cause panics"
fix in the editor to be more robust
Release Notes:
- Fixed panic with completion ranges and autoclose regions interop
