# Why

I have spotted that Keymap Editor filter input (editor) is misaligned
vertically.

# How

Switch the input wrapper to flex layout, use `items_center` to align
editor vertically in center of the wrapper.

Release Notes:

- Fixed Keymap Editor filter input alignment

# Test plan

I have tested the change locally and compared the UI before and after,
to make sure that change does not affect the size of the wrapper
element.

BusyBox's off brand `wget` does not have support for the `--method`
argument, which makes `zed` incapable of downloading the remote server
unless the _☙authentic❧_ one is installed. Removing this should fix the
issue. Couldn't find much about guidelines on how the code is supposed
to be formatted, so I opted for commenting the line out with an
explanation.

This reverts commit ed7bd5a8ed6cbda563c4e6f1acb66e13f545718b.

We noticed this PR causes the editor to hang if you hold down any of the
menu item actions like ctrl+z, ctrl+x, etc


Release Notes:

combination is held down

Uses the previously merged denoising crate (and fixes a bug in it that
snug in during refactoring) to add denoising to the microphone input. 

Adds automatic volume control for microphone and output.

Prepares for migrating to 16kHz SR mono:
The experimental audio path now picks the samplerate and channel count depending on a setting. It can handle incoming streams with both the current (future legacy) and new samplerate & channel count. These are url-encoded into the livekit track name

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

When using Blade rendering (Linux platforms and self-compiled builds
with the Blade renderer enabled), Zed reads `ZED_FONTS_GAMMA` and
`ZED_FONTS_GRAYSCALE_ENHANCED_CONTRAST` environment variables for the
values to use for font rendering.

`ZED_FONTS_GAMMA` corresponds to
[getgamma](https://learn.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwriterenderingparams-getgamma)
values.
Allowed range [1.0, 2.2], other values are clipped.
Default: 1.8

`ZED_FONTS_GRAYSCALE_ENHANCED_CONTRAST` corresponds to
[getgrayscaleenhancedcontrast](https://learn.microsoft.com/en-us/windows/win32/api/dwrite_1/nf-dwrite_1-idwriterenderingparams1-getgrayscaleenhancedcontrast)
values.
Allowed range: [0.0, ..), other values are clipped.
Default: 1.0

# 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).

cc @davidlattimore from Wild, just fyi

# Tasks

- [x] Measure Wild build, incremental build, and runtime performance in
different scenarios
- [x] Remove the Linux linker config from `.cargo/config.toml` in the
tree
- [x] Test rope benchmarks etc
- [x] Set the linker to Mold in CI 
- [x] Add instructions to use Wild or Mold into `linux.md`
- [x] Add a script to download Wild
- [x] Measure binary size
- [x] Recommend Wild from `scripts/linux`

# Benchmarks 

| | wild 0.6 (rust 1.89) | mold 2.37.1 (1.89) | lld (rust 1.90) | wild
advantage |
| -- | -- | -- | -- | -- |
| clean workspace build | 176s | 184s | 182s | 5% faster than mold |
| nextest run workspace after build | 137s | 142s | 137s | in the noise?
|
| incremental rebuild | 3.9s | 5.0s | 6.6s | 22% faster than mold | 

I didn't observe any apparent significant change in runtime performance
or binary size, or in the in-tree microbenchmarks.

# Why

In Git Panel, it felt to me that repo and branch separator can be
slightly demphasized (since it is not-interactable) and separated a bit
more from the repo and branch popover triggers.

# How

Use `icon_muted` color for the separator (happy to know if this is an
abuse of the UI styleguide 😄), add one pixel horizontal spacing around
the `/` character.

Release Notes:

- Improved appearance of repo and branch separator in Git Commit Panel

# Test plan

I have tested the change locally and compared the UI before and after to
make sure it feels right.

Closes #37601

Edit: Original issue https://github.com/zed-industries/zed/issues/25744
is fixed for Zeta in this PR. For Copilot, it will be covered in a
follow-up. In the case of Copilot, even after discarding, we still get a
prediction on suggest, which is a bug.

Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).
