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.

# 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.

Expands on #38543 (notably allows setting importance categories and
weights on tests, and a lot of internal refactoring) because I couldn't
help myself. Also allows exporting runs to json and comparing across them. See code for docs.
Release Notes:

Add an auto-profiler for our tests, to hopefully allow better triage of
performance impacts resulting from code changes. Comprehensive usage
docs are in the code.
Currently, it uses hyperfine under the hood and prints markdown to the
command line for all crates with relevant tests enabled. We may want to
expand this to allow outputting json in the future to allow e.g.
automatically comparing the difference between two runs on different
commits, and in general a lot of functionality could be added (maybe
measuring memory usage?).
It's enabled (mostly as an example) on two tests inside `gpui` and a
bunch of those inside `vim`. I'd have happily used `cargo bench`, but that's nightly-only.
Release Notes:

It is unused and generates a warning
```
LINK : warning LNK4044: unrecognized option '/fuse-ld=lld'; ignored
```
If in the future we want to give `lld-link.exe` a try, we can set
```toml
linker = "lld-link.exe"
```
instead. At the time of writing, my tests have shown that there is no
real difference between `lld-link` and `link` in terms of linking speed.

The installer, uninstaller, and the Zed binary files are all signed
using Microsoft’s newly launched Trusted Signing service. For
demonstration purposes, I have used my own account for the signing
process.
For more information about Trusted Signing, you can refer to the
following links:

Preview](https://techcommunity.microsoft.com/blog/microsoft-security-blog/trusted-signing-is-in-public-preview/4103457)
- [Overview of Azure Trusted
Signing](https://learn.microsoft.com/en-us/azure/trusted-signing/overview)
**TODO:**
- [x] `InnoSetup` script to setup an installer
- [x] Signing process
- [x] `Open with Zed` in right click context menu (by using sparse
package)
- [x] Integrate with `cli`
- [x] Implement `cli` (#25412)
- [x] Pack `cli.exe` into installer
- [x] Implement auto updating (#25734)
- [x] Pack autoupdater helper into installer
- [x] Implement dock menus
- [x] Add `Recent Documents` entries (#26369)
- [x] Make `zed.exe` aware of sigle instance (#25412)
- [x] Properly handle dock menu events (#26010)
- [x] Handle `zed://***` uri
**Materials needed:**
- [ ] Icons
- [ ] App icon for all channels (#9571)
- [ ] Associated file icons, at minimum a default icon
([example](https://github.com/microsoft/vscode/tree/main/resources/win32))
- [ ] Logos for installer wizard
- [ ] Icons for appx
- [x] Code signing
- [x] Secrets: AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET,
ACCOUNT_NAME, CERT_PROFILE_NAME
- [x] Other constants: ENDPOINT, Identity Signature (i.e. `CN=Junkui
Zhang, O=Junkui Zhang, L=Wuhan, S=Hubei, C=CN`)

- bump our livekit version to include a fix for a crane bug (TODO: add
link when an issue is filed on crane)
- switch to a clang stdenv for both linux and macos
- manually unify versions of our notify crate
- remove old linker flags which were only needed for livekit
- fix an issue where RUSTFLAGS shadowed the rustflags from cargo configs

## Problem
Running `cargo run .` twice in Zed repository required a rebuild two
times in a row. The second rebuild was triggered around libz-sys, which
in practice caused a rebuild of the ~entire project.
Some concrete examples:
```
cargo test -p project # Requires a rebuild (warranted)
cargo run .
cargo test -p project # Requires a rebuild (unwarranted)
```
or
```
cargo run . # Requires a rebuild (warranted)
cargo run . # Requires a rebuild (unwarranted)
```
## What's going on
Zed build script on MacOS sets MACOSX_DEPLOYMENT_TARGET to 10.15. This
is fine. However, **cargo propagates all environment variables to child
processes during `cargo run`**. This then affects Rust Analyzer spawned
by dev Zed - it clobbers build cache of whatever package it touches,
because it's behavior is not same between running it with `cargo run`
(where MACOS_DEPLOYMENT_TARGET gets propagated to child Zed) and running
it directly via `target/debug/zed` or whatever (where the env variable
is not set, so that build behaves roughly like Zed Dev.app).
## Solution
~We'll unset that env variable from user environment when we're
reasonably confident that we're running under `cargo run` by exploiting
other env variables set by cargo:
https://doc.rust-lang.org/cargo/reference/environment-variables.html
CARGO_PKG_NAME is always set to `zed` when running it via `cargo run`,
as it's the value propagated from the build.~
~The alternative I've considered is running [via a custom
runner](https://doc.rust-lang.org/cargo/reference/config.html#targetcfgrunner),
though the problem here is that we'd have to use a shell script to unset
the env variable - that could be problematic with e.g. fish. I just
didn't want to deal with that, though admittedly it would've been
cleaner in other aspects.~
Redact all above. We'll just set MACOSX_DEPLOYMENT_TARGET regardless of
whether you have it in your OG shell environment or not.

While working on PR #23117, I noticed that the Windows runner in our CI
setup doesn't seem to respect the settings defined in
`.cargo/config.toml`. With @SomeoneToIgnore ’s help, Kirill and I
realized this issue isn’t limited to the Windows runner—all of our
runners disregard the configurations in `.cargo/config.toml`.
Later, @osiewicz suggested an excellent workaround. I conducted some
tests on PR #23117 and found that the solution works as intended.
Personally, I prefer using environment variables for global
configuration. However, according to the documentation
[here](https://doc.rust-lang.org/cargo/reference/config.html), it seems
that environment variables always override the settings in
`.cargo/config.toml`.

Similar to #20826 but keeps the Swift implementation. There were quite a
few changes in the `call` crate, and so that code now has two variants.
Closes#13714
Release Notes:
- Added preliminary Linux support for voice chat and viewing
screenshares.

Issues found:
* audio does not work well with various set-ups using USB
* switching audio during initial join may leave the client with no audio
at all
* audio streaming is done on the main thread, beachballing certain
set-ups
* worse screenshare quality (seems that there's no dynamic scaling
anymore, compared to the Swift SDK)
This reverts commit 1235d0808e.

This PR sets up a `cargo xtask clippy` command for running `cargo
clippy` with our defined set of options.
The intent is to make this easier to manage as we start enabling more
Clippy rules.

Due to modification of .cargo/config.toml your `cargo build` should pick
this change up automatically. Use `legacy` instead of `v0` if you find
yourself in need of old mangling scheme for whatever reason
Release Notes:
- Improved precision of backtraces in application crashes
