Make `resolve_full_path` use the appropriate separators, and return a
`String`.

As part of fixing the fallout from that type change, this also fixes a
bunch of places in the agent code that were using `std::path::Path`
operations on paths that could be non-local, by changing them to operate
instead on strings and use the project's `PathStyle`.

This clears the way a bit for making `full_path` also return a string
instead of a `PathBuf`, but I've left that for a follow-up.

Closes #38553 
Release Notes:

- Fixed wrong AssetKind specified on linux for ty 


As discussed in the linked issue. All of the non windows assets for ty
are `tar.gz` files. This change applies that fix.

Release Notes:

- When `helix_mode = true`, modes are called without the `HELIX_` prefix
in the UI:
  `HELIX_NORMAL` becomes `NORMAL`
  `HELIX_SELECT` becomes `SELECT`
- (breaking change) Helix users should remove `"default_mode":
"helix_normal"` from their settings. This is now the default when
`"helix_mode": true`.

Consolidate constructors and accessors.

Release Notes:

- Fixed editor inlay hints incorrectly using status theming when syntax
theming is available

Previously, a theme's `style.syntax.hint` object is completely ignored,
and `style.hint` `style.hint.background` are used instead. However,
these seem to be related to status hints, such as the inline git blame
integration.

For syntax hints (as given by an LSP), the reasonable assumption would
be that the `style.syntax.hint` object is used instead, but it isn't.
This means that defining other style characteristics (`font_style`, for
example) does nothing.

I've fixed the issue in a backward-compatible way, by using the theme
`syntax` `HighlightStyle` as the base for inlay hint styling, and
falling back to the original `status` colors should the syntax object
not contain the color definitions.

 With the following theme settings:
```jsonc
{
  "hint": "#ff00ff",                    // Status hints (git blame, etc.)
  "hint.background": "#ff00ff10",
  "syntax": {
    "hint": {
      "color": "#ffffff",               // LSP inlay hints
      "background_color": "#ffffff10",
      "font_style": "italic",           // Now properly applied
      "font_weight": 700
    }
  }
}
```


Current behavior:
<img width="896" height="201" alt="image"
src="https://github.com/user-attachments/assets/e89d212f-ed7e-4d27-94e4-96d716e229d2"
/>

Italics and font weight are ignored. Uses status colors instead.

Fixed behavior:
<img width="896" height="202" alt="image"
src="https://github.com/user-attachments/assets/f14ed2c3-bb60-4b74-886d-6b409d338714"
/>

Italics and font weight are used properly. Status color is preserved for
the git blame status, but correct syntax colors are used for the inlay
hints.

Closes #38620

`Url::from_file_path` and `Url::from_directory_path` assume the path
style of the target they were compiled for, so we can't use them in
general. So, switch from `file://` to encoding the absolute path (for
mentions that have one) as a query parameter, which works no matter the
platforms. We'll still parse the old `file://` mention URIs for
compatibility with thread history.

# 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.

# Test plan

BusyBox's off brand `wget` does not have support for the `--method`

with the Blade renderer enabled), Zed reads `ZED_FONTS_GAMMA` and

`ZED_FONTS_GAMMA` corresponds to

# 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.
