I noticed we had some typos that were getting through CI, but it looks
like the new version of `typos` catches them. So I updated it and fixed
them.

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.

Retrieval stats will now use polars to build a big data frame for
references with the cartesian product of LSP declarations and retrieved
declaration candidates (with all their score components) and rebuilds
the stats summary on top of it.
This data frame is written to a `.parquet` file, which we can load into
advanced analytics tools (such as Metabase), so we can explore our
scoring distributions and find ways to improve retrieval, and then train
the decision tree.

This moves some of the changes made in
https://github.com/zed-industries/zed/pull/39543 to the `publish_gpui`
script.
This PR also updates that script to use `gpui_` instead of `zed-` (where
possible)

This PR is a follow-up to #39090 and addresses two issues:
* Moves `conpty.dll` and `OpenConsole.exe` out of the `bin` folder to
prevent other programs from using them.
* Updates these files only after Zed exits, avoiding update failures due
to file locks.

# Background
Several users have noted that the terminal shipped with Zed on Windows
is either misbehaving or missing several features including lack of
consistent clearing behaviour. After some investigation which included
digging into the Microsoft Terminal project and VSCode editor, it turns
out that the pseudoconsole provided by Windows OS is severely outdated
which manifests itself in problems such as lack of clearing behaviour,
etc. Interestingly however, neither MS Terminal nor VSCode exhibit this
limitation so the question was why. Enter custom `conpty.dll` and
`OpenConsole.exe` runtime. These are updated, developed in MS Terminal
tree subprojects that aim to replace native Windows API as well as
augment the `conhost.exe` process that runs by default in Windows. They
also fix all the woes we had with the terminal on Windows (there is a
chance that ctrl-c behaviour is also fixed with these, but still need to
double check that this is indeed the case). This PR ensures that Zed
also benefits from the update pseudoconsole API.
# Proposed approach
It is possible to fork MS Terminal and instrument the necessary
subprojects for Rust-awareness (using `cc-rs` or otherwise to compile
the C++ code and then embed it in Rust-produced binaries for easier
inclusion in projects) but it comes at a cost of added complexity,
maintenance burden, etc. An alternative approach was proposed by
@reflectronic to download the binary from the official Nuget repo and
bundle it for release/local use. This PR aims to do just that.
There are two bits to this PR:
1. ~~when building Zed locally, and more specifically, when the `zed`
crate is being built, we will strive to download and unpack the binaries
into `OUT_DIR` provided by `cargo`. We will then set
`ZED_CONPTY_INSTALL_PATH=${OUT_DIR}/conpty` and use it at runtime in Zed
binary to tweak the loader's search path with that additional path. This
effectively ensures that Zed built from source on Windows has full
terminal support.~~ EDIT: after several discussions offline, we've
decided that keeping it minimal will serve us best, meaning: when
developing locally it is up to the developer of Zed to install
`conpty.dll` and put it in the loader's search path.
2. when bundling Windows release, we will download and unpack the nuget
package into Zed's bundle which will ensure it is installed in the same
directory as Zed by the installer.
**Note** I realise that 1. may actually not be needed - instead we could
leave that bit for the user who wants to run Zed from source to ensure
that they have `conpty.dll` in the loader's search path. I'd love to
hear opinions on this!

There's a mismatch between the URL used here and the one that's referred
to in `build_zed_cloud_url`, which prevents using the script on Windows.
A previous PR changed the script to use `127.0.0.1` instead of
`localhost` because of supposed URL parsing issues, but we were unable
to reproduce those.

# Summary
Today, Zed uses Mold on Linux, but Wild can be significantly faster.
On my machine, Wild is 14% faster at a whole-tree clean build, 20%
faster on an incremental build with a minimal change, and makes no
measurable effect on runtime performance of tests.
However, Wild's page says it's not yet ready for production, so it seems
to early to switch for production and CI builds.
This PR keeps using Mold in CI and lets developers choose in their own
config what linker to use. (The downside of this is that after landing
this change, developers will have to do some local config or it will
fall back to the default linker which may be slower.)
[Wild 0.6 is out, and their announcement has some
benchmarks](https://davidlattimore.github.io/posts/2025/09/23/wild-update-0.6.0.html).

I ran `scripts/linux` on Debian Trixie 13. It suggested manually
installing Mold, but [mold](http://packages.debian.org/mold) is packaged
on Debian and so we could install it automatically.
The version packaged there seems to work well enough for `cargo t` to
pass, at least.
## Tested
```
; sudo apt remove mold libstdc++-14-dev
... uninstalls them
; ./script/linux
The following NEW packages will be installed:
build-essential clang clang-19 clang-tools-19 g++ g++-14 g++-14-x86-64-linux-gnu g++-x86-64-linux-gnu libstdc++-14-dev mold

Closes #ISSUE
Centralizes the references to the `ZED_STATELESS` env var into a single
location in a new crate named `zed_env_vars`
Release Notes:
- N/A *or* Added/Fixed/Improved ...
I'm not sure we actually want to be using `debug-info=unpacked` and then
running `dsymutil` with `--flat`, but for now the minimal change to get
this working is to manually specify the flattened, uncompressed debug
info file for upload, which in turn will cause `sentry-cli` to pick up
on source-info for the zed binary.
I think in the future we should switch to `packed` debug info, both for
the zed binary _and_ the remote server, and then we can tar up the
better supported `dSYM` folder format rather than the flat dwarf
version.

## Summary
This PR updates the install script to respect the `TMPDIR` environment
variable when creating temporary directories.
## Motivation
Some environments have non-standard temporary directory locations or
restrictions on `/tmp`. This change allows users to specify an
alternative temporary directory by setting the `TMPDIR` environment
variable.
## Changes
- Check if `TMPDIR` is set and points to a valid directory
- Use `$TMPDIR` for temporary files if available
- Fall back to `/tmp` if `TMPDIR` is not set or invalid
## Testing
Tested the script with:
- `TMPDIR` unset (uses `/tmp` as before)
- `TMPDIR` set to a valid directory (uses specified directory)
- `TMPDIR` set to an invalid path (falls back to `/tmp`)
This change maintains backward compatibility while adding flexibility
for environments with non-standard temporary directory requirements.

You will still connect the same way—using the `zed-local` script—but
will need to be running an instance of Cloud locally.
