This PR improves key handling on Windows by moving the
`TranslateMessage` call from the message loop to after we handled
`WM_KEYDOWN`. This brings Windows behavior more in line with macOS and
gives us finer control over key events. As a result, Vim keybindings now
work properly even when an IME is active. The trade-off is that it might
introduce a slight delay in text input.

This brings back [linux(x11): Add support for pasting images from
clipboard · Pull Request
#29387](https://github.com/zed-industries/zed/pull/29387) while fixing
#30523 (which caused it to be reverted).
Commit message from that PR:
> Closes:
https://github.com/zed-industries/zed/pull/29177#issuecomment-2823359242
>
> Removes dependency on
[quininer/x11-clipboard](https://github.com/quininer/x11-clipboard) as
it is in [maintenance
mode](https://github.com/quininer/x11-clipboard/issues/19).
>
> X11 clipboard functionality is now built-in to GPUI which was
accomplished by stripping the non-x11-related code/abstractions from
[1Password/arboard](https://github.com/1Password/arboard) and extending
it to support all image formats already supported by GPUI on wayland and
macos.
>
> A benefit of switching over to the `arboard` implementation, is that
we now make an attempt to have an X11 "clipboard manager" (if available
- something the user has to setup themselves) save the contents of
clipboard (if the last copy operation was within Zed) so that the copied
contents can still be pasted once Zed has completely stopped.
Before the fix for reapply, it was iterating through the formats and
requesting conversion to each. Some clipboard providers just respond
with a different format rather than saying the format is unsupported.
The fix is to use this response if it matches a supported format. It
also now typically avoids this iteration by requesting the `TARGETS` and
taking the highest precedence supported target.
Closes#30523

- Linux (X11): Restored the ability to paste images.

Using lldb to disassemble `CVHWTime::reset()` (and the AI to interpret
it), the crash is caused by dereferencing the pointer at the start of
the CVHWTime struct + 0x1c8. In this case the pointer has (the clearly
nonsense) value 0x2e (and 0x2e + 0x1c8 = 0x1f6, the failing address).
As to how this could happen...
Looking at the implementation of `CVDisplayLinkRelease`, it calls
straight into `CFRelease` on the main thread; and so it is not safe to
call `CVDisplayLinkRelease` concurrently with other threads that access
the CVDisplayLink. While we already stopped the display link, it turns
out that `CVDisplayLinkStop` just sets a flag on the struct to instruct
the io-thread to exit "soon", and returns immediately. That means we
don't know when the other thread will actually exit, and so we can't
safely call `CVDisplayLinkRelease`.
So, for now, we just leak these objects. They should be created
relatively infrequently (when the app is foregrounded/backgrounded), so
I don't think this is a huge problem.
Release Notes:
- Fix a rare crash on macOS when putting the app in the background.
Adds a validation step to docs preprocessing so that actions referenced
in docs are checked against the list of all registered actions in GPUI.
In order for this to work properly, all of the crates that register
actions had to be importable by the `docs_preprocessor` crate and
actually used (see [this
comment](https://github.com/zed-industries/zed/commit/ef730c486c41030777d07ab0ee62cecc47211aab#diff-2674caf14ae6d70752ea60c7061232393d84e7f61a52915ace089c30a797a1c3)
for why this is challenging).
In order to accomplish this I have moved the entry point of zed into a
separate stub file named `zed_main.rs` so that `main.rs` is importable
by the `docs_preprocessor` crate, this is kind of gross, but ensures
that all actions that are registered in the application are registered
when checking them in `docs_preprocessor`. An alternative solution
suggested by @mikayla-maki was to separate out all our `::init()`
functions into a lib entry point in the `zed` crate that can be imported
instead, however, this turned out to be a far bigger refactor and is in
my opinion better to do in a follow up PR with significant testing to
ensure no regressions in behavior occur.
Release Notes:
- N/A
Modify the `replace_and_mark_text_in_range` method in the `Editor` to
keep the cursor at the start of the preedit range during IME
composition. Previously, the cursor would move to the end of the preedit
text with each update, causing the IME candidate box to shift (e.g.,
when typing pinyin with Fcitx5 on Wayland). This change ensures the
cursor and candidate box remain fixed until the composition is
committed, improving the IME experience.

Prep for https://github.com/zed-industries/zed/pull/32040
Currently, there’s no way to modify the cursor style of the active drag
state after dragging begins. However, there are scenarios where we might
want to change the cursor style, such as pressing a modifier key while
dragging. This PR introduces an API to update and read the current
active drag state cursor.

The before version GPUI used `Cancel` for cancel text, if we use
non-English text (e.g.: "取消" in Chinese), then the press `Esc` to cancel
will not work.
So this PR to change it by use `PromptButton` to instead the `&str`,
then we can use `PromptButton::cancel("取消")` for the `Cancel` button.
Run `cargo run -p gpui --example window` to test.

This method was added in #20649 to be an alternative of `occlude` which
allows scroll events. It seems a bit arbitrary to only stop left mouse
downs, so this seems like it's probably an improvement.
Release Notes:
- N/A
tl;dr: This adds `.block_mouse_except_scroll()` which should typically
be used instead of `.occlude()` for cases when the mouse shouldn't
interact with elements drawn below an element. The rationale for
treating scroll events differently:
* Mouse move / click / styles / tooltips are for elements the user is
interacting with directly.
* Mouse scroll events are about finding the current outer scroll
container.
Most use of `occlude` should probably be switched to this, but I figured
I'd derisk this change by minimizing behavior changes to just the 3 uses
of `block_mouse_except_scroll`.
GPUI changes:
* Added `InteractiveElement::block_mouse_except_scroll()`, and removes
`stop_mouse_events_except_scroll()`
* Added `Hitbox::should_handle_scroll()` to be used when handling scroll
wheel events.
* `Window::insert_hitbox` now takes `HitboxBehavior` instead of
`occlude: bool`.
- `false` for that bool is now `HitboxBehavior::Normal`.
- `true` for that bool is now `HitboxBehavior::BlockMouse`.
- The new mode is `HitboxBehavior::BlockMouseExceptScroll`.
* Removes `Default` impl for `HitboxId` since applications should not
manually create `HitboxId(0)`.
Release Notes:
- N/A
Editing JSON styles is not very helpful for bringing style changes back
to the actual code. This PR adds a buffer that pretends to be Rust,
applying any style attribute identifiers it finds. Also supports
completions with display of documentation. The effect of the currently
selected completion is previewed. Warning diagnostics appear on any
unrecognized identifier.

Adds a `#[derive_inspector_reflection]` macro which allows these methods
to be enumerated and called by their name. The macro code changes were
95% generated by Zed Agent + Opus 4.
Release Notes:
* Added an element inspector for development. On debug builds,
`dev::ToggleInspector` will open a pane allowing inspecting of element
info and modifying styles.
- Use compile time `cfg` macro instead of a runtime check
- Use `Modifiers` instead of a bunch of `bool` when parsing a
`Keystroke`.
Release Notes:
- N/A
Open inspector with `dev: toggle inspector` from command palette or
`cmd-alt-i` on mac or `ctrl-alt-i` on linux.

* Picking of elements via the mouse, with scroll wheel to inspect
occluded elements.
* Temporary manipulation of the selected element.

the core of an inspector.

Part of #31174
Because the keyboard layout parameter wasn’t set correctly, characters
don’t show up properly when using the German layout at launch.
To reproduce:
Switch to the German layout, launch Zed, and press the `7` key. it
should output `7`, but instead it outputs `è`.

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

Reverts zed-industries/zed#31022
Sorry @mikayla-maki, I found that things are more complicated than I
thought.
The lines returned by shape_text must maintain the same length as all
the original characters, otherwise the subsequent offset needs to always
consider the difference of `\r\n` or `\n` to do the offset.
Before, we only needed to add +1 after each offset after the line, but
now we need to consider +1 or +2, which is much more complicated.

Today I check the shape_text result on Windows, I get:

/>
Here the `shape_text` split logic I think it should use `lines` method,
not `split('\n')`, the newline on Windows is `\r\n`.

When we use `window_handle` to draw WebView on Windows, this will crash
by:
This error caused by when used WebView2.

```
Try this https://github.com/tauri-apps/wry/pull/1383 on Windows can
replay the crash.
In fact, we had done [a similar fix around August last
year](https://github.com/huacnlee/zed/pull/6), but we used the unsafe
method to avoid crashes in that version, we felt that it was not a good
change, so we do not make PR.
Today @sunli829 thought about it again and changed the method. Now using
`try_borrow_mut` is similar to the previous `borrow_mut`.

Part of #29144, this PR completely rewrites the key handling logic on
Windows, making it much more consistent with how things work on macOS.
However, one remaining issue is that on Windows, we should be using

addressed in #29144.
