Wild changed in 0.6.0 to using gzip rather than xz, and changed the
format of the package name.

Release Notes:
- N/A
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).

# 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.

Also removed the symbolicate script, which we could replace with a
`minidump-stackwalk` wrapper that downloaded sources/unstripped binaries
from github releases if that's helpful for folks.

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
; cargo t

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.

This PR reworks authentication for developing Zed against a local
version of Cloud and/or Collab.
You will still connect the same way—using the `zed-local` script—but
will need to be running an instance of Cloud locally.

The license file is not properly linked to actual license. This was
casued due to new-crate script linking the license to wrong file. Fixed
both of them.

Current main shows this on `script/generate-licenses`:
```
[WARN] failed to validate all files specified in clarification for crate ring 0.17.14: checksum mismatch, expected '76b39f9b371688eac9d8323f96ee80b3aef5ecbc2217f25377bd4e4a615296a9'
```
Ring fixed it's licenses ambiguity upstream. This warning was
identifying that their license text (multiple licenses concatenated) had
changed (sha mismatch) and thus our license clarification was invalid.
Tested the script to confirm this [now
fails](https://github.com/zed-industries/zed/actions/runs/16118890720/job/45479355992?pr=34008)
under CI and then removed the ring clarification because it is no longer
required and now passes.

While creating a new crate I realised the License symlink and path are
broken. The symlink was broken for LICENSE-GPL. Also the file created in
the new crate was not using the expected file name as per the
check-license script which was failing due to wrong filename in the new
crate. I fixed that as well.

This format is enabled for Google models as they seem to prefer it.
A relevant unit eval's pass rate has increased from 0.77 to 0.98.
Diff-fenced format looks like this (markdown fences and a line hint are
optional):
```diff
<<<<<<< SEARCH line=42
...
=======
...
>>>>>>> REPLACE
```
Release Notes:
- Agent: Gemini models now use the diff-fenced format when making edits
Motivation for the `cmd-` check is that there were a couple keybindings
using `cmd-` in the linux keymap and so these were bound to super /
windows
