Closes https://github.com/zed-industries/zed/issues/31106

This fixes an issue where you would have to manually uninstall the
release extension before installing the dev extension in case that is
locally installed.

Release Notes:

- Installing a dev extension will now automatically remove the release
extension should it be installed.

After this the doctests will be run in CI to check that the examples are
still accurate.

Note that doctests aren't run by Nextest: you can run them locally with
`cargo test --doc`.

Summary:
* Run tests from CI
* Loosen an exact float comparison to match approximately (otherwise it
fails)
* Fixed one actual bug in the tests for `dilate` where the test code
assumed that `dilate` mutates `self` rather than returning a new object
* Add some `must_use` on some functions that seemed at risk of similar
bugs, following the Rust stdlib style to add it where ignoring the
result is almost certainly a bug.
* Fix some cases where the doc examples seem to have gone out of date
with the code
* Add imports to doctests that need them
* Add some dev-dependencies to make the tests build
* Fix the `key_dispatch` module docstring, which was accidentally
attached to objects within that module
* Skip some doctest examples that seem like they need an async
environment or that just looked hard to get running

AI usage: I asked Claude to do some of the repetitive tests. I checked
the output and fixed up some things that seemed to not be in the right
spirit of the test, or too longwinded.

I think we could reasonably run the tests on only Linux to save CI
CPU-seconds and latency, but I haven't done that yet, partly because of
how it's implemented in the action.

Closes #ISSUE

Release Notes:

- Fixed an issue where the `line_indicator_format` setting would not
update based on the value in `settings.json`

Using `window.use_state` made the element IDs match between elements,
thus causing the same menu to be shared for drop down menus. I switched
to `window.use_keyed_state` and used a value's path as it's element id

Adds a `named_directory_icons` field to the icon theme that can be used
to specify a collection of icons for collapsed and expanded folders
based on the folder name.

The `named_directory_icons` is a map from the folder name to a
`DirectoryIcons` object containing the paths to the expanded and
collapsed icons for that folder:

```json
{
  "named_directory_icons": {
    ".angular": {
      "collapsed": "./icons/folder_angular.svg",
      "expanded": "./icons/folder_angular_open.svg"
    }
  }
}

```

Closes #20295

Closes #ISSUE

This PR continues work from #32821 by adding a stash entry picker for
pop/drop operations. Additionally, the stash pop action in the git panel
is now disabled when no stash entries exist, preventing error logs from
attempted pops on empty stashes.

- Added a stash picker to pop and drop a specific stash entry
- Disabled the stash pop action on the git panel when no stash entries
exist
- Added git stash apply command
- Added git stash drop command

This fixes an issue where we would not update neither the path nor the
editor that was listened to during follow mode, which in turn would
cause the preview to become stale.

Fix here is to update the subscription whenever the active item changes
and also update the associated path accordingly.


Release Notes:

- Fixed an issue where the SVG preview would not update when following
the active editor.

Menu items in the context menu component have the ability to display a
documentation aside popover. However, because this docs aside popover
was setup as a sibling flex container to the actual menu popover, if the
menu had a short amount of items and the docs popover is bigger than the
menu, this flickering would happen, making it essentially unusable:


https://github.com/user-attachments/assets/74956254-fff6-4c5c-9f79-02998c64a105

So, this PR makes the docs aside popover in wide window sizes
absolutely-positioned relative to the menu container, which removes all
flickering. On top of that, I'm adding a `DocumentationEdge` enum that
allows to control the edge anchor of the docs aside, which is useful in
this particular mode selector example to make the layout work well.


https://github.com/user-attachments/assets/a3e811e1-86b4-4839-a219-c3b0734532b3

When the window is small, the docs aside continue to be a sibling flex
container, which causes a super subtle shift in the items within the
menu popover. This is something I want to pursue fixing, but didn't want
to delay this PR too much.

Release Notes:

Instead of passing CWD verbatim from the Windows host with backslashes

Resolves Incorrect Secret error in Secret Service integration

Closes #34024 

Release Notes:

- Fixed Secret Service integration sometimes producing `Incorrect
secret` error

This removes the `gemini-and-native` and `claude-code` feature flags.
Also, I removed a bunch of unused agent1 code that we do not need
anymore.

Initially I wanted to remove much more of the `agent` code, but noticed
some things that we need to figure out first:
- The inline assistant + context strip use `Thread`/`ContextStore`
directly
- We need some replacement for `ToolWorkingSet`, so we can access
available tools (as well as context server tools) in other places, e.g.
the agent configuration and the configure profile modal

Release Notes:
- Helix will no longer sometimes fall out into "normal" mode, will
remain in "helix normal" (example: vv)
- Added dedicated "helix select" mode that can be targeted by
keybindings

Known issues:
- [ ] Helix motion, especially surround-add will not properly work in
visual mode, as it won't call `helix_move_cursor`. It is possible
however to respect self.mode in change_selection now.
- [ ] Some operations, such as `Ctrl+A` (increment) or `>` (indent) will
collapse selection also. I haven't found a way to avoid it.

When working on the git stash picker PR (#35927) I notice that my test
was detected as a binary file on the git diff view and on GitHub. This
was due to the fact that I was using the literal char \0 (instead of a
proper representation like `\x00` or `\u{0000}`) character in my test
strings. This causes problems with git diff and GitHub's diff viewer,
and a reviewer might even assume that the file is corrupted, not
viewable or even malicious.

Looking at the rest of the codebase, only at `crates/git/src/commit.rs`
this character was used, so I replaced it with `\x00` which is a more
common representation of the null character in Rust strings.

It can also be seen that the PR that introduced this code, can't be
viewed properly on Github:
https://github.com/zed-industries/zed/pull/27636/files#diff-31114f0b22306b467482573446f71c638277510b442a10e60dd9a8667ccd93c3

Closes #ISSUE

Release Notes:

- Use `\x00` representation instead of literal null character in strings
to improve compatibility with git diff and GitHub's diff viewer.

Since the file is not viewable from the "Files changed" tab on Github,
this is the changed code:


https://github.com/zed-industries/zed/blob/dcd743aca494ec0217a2d7751150ca9e456012f4/crates/git/src/commit.rs#L66-L74

Updates #19350

Release Notes:

- Add `pane::SplitAndMove{Up,Down,Left,Right}` to allow creating a split
without cloning the current buffer.

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.

This is for both ACP and the regular agent. Previously we would always

#37337 Made `AutoUpdateSetting` `FileContent =
AutoUpdateSettingsContent` which caused a deserialization bug to occur
because the field it was wrapping wasn't optional. Thus serde would
deserialize the wrapped type `bool` to its default value `false`
stopping the settings load function from reading the correct default
value from `default.json`

I also added a log message that states when the auto updater struct is
checking for updates to make this easier to test.

Release Notes:

- fix auto update defaulting to false

### Background

Zed extensions use WASI to access the file-system. They only have
read-write access to one specific folder called their work dir. But
extensions do need to be able to *refer* to other arbitrary files on the
user's machine. For instance, extensions need to be able to look up
existing binaries on the user's `PATH`, and request that Zed invoke them
as language servers. Similarly, extensions can create paths to files in
the user's project, and use them as arguments in commands that Zed
should run. For these reasons, we pass *real* paths back and forth
between the host and extensions; we don't try to abstract over the
file-system with some virtualization scheme.

On Windows, this results in a bit of mismatch, because `wasi-libc` uses
*unix-like* path conventions (and thus, so does the Rust standard
library when compiling to WASI).

### Change 1 - Fixing `current_dir`

In order to keep the extension API minimal, extensions use the standard
library function`env::current_dir()` to query the location of their
"work" directory. Previously, when initializing extensions, we used the
`env::set_current_dir` function to set their work directory, but on
Windows, where absolute paths typically begin with a drive letter, like
`C:`, the [`wasi-libc` implementation of
`chdir`](https://github.com/WebAssembly/wasi-libc/blob/d1793637d8afcdc730408e7b6a19a050c3336ce7/libc-bottom-half/sources/chdir.c#L21)
was prepending an extra forward slash to the path, which caused
`current_dir()` to return an invalid path.

See https://github.com/bytecodealliance/wasmtime/issues/10415

In this PR, I've switched our extension initialization function to
*bypass* wasi-libc's `chdir` function, and instead write directly to
wasi-libc's private, internal state. This is a bit of a hack, but it
causes the `current_dir()` function to do what we want on Windows
without any changes to extensions' source code.

### Change 2 - Working around WASI's relative path handling

Once `current_dir` was fixed (giving us correct absolute paths on
Windows), @kubkon and I discovered that without the spurious leading `/`
character, windows absolute paths were no longer accepted by Rust's
`std::fs` APIs, because they were now recognized as relative paths, and
were being appended to the working directory.

We first tried to override the `__wasilibc_find_abspath` function in
`wasi-libc` to make it recognize windows absolute paths as being
absolute, but that functionality is difficult to override. Eventually
@kubkon realized that we could prevent WASI-libc's CWD handling from
being linked into the WASM file by overriding the `chdir` function.
wasi-libc is designed so that if you don't use their `chdir` function,
then all paths will be interpreted as relative to `/`. This makes
absolute paths behave correctly. Then, in order to make *relative* paths
work again, we simply add a preopen for `.`. Relative paths will match
that.

### Next Steps

This is a change to `zed-extension-api`, so we do need to update every
Zed extension to use the new version, in order for them to work on
windows.

@maxdeviant We can eventually turn down the panic telemetry endpoint,
but should probably leave it up while there's still a bunch of stable
users hitting it.

@maxbrunsfeld We're optimistic that this change also fixed the macos
crashed-thread misreporting. We think it was because the
`CrashContext::exception` was getting set to `None` only on macos, while
on linux it was getting a real exception value from the sigtrap. Now
we've unified and it uses `SIGABRT` on both platforms (I need to double
check that this works as expected for windows).

We unconditionally set `RUST_BACKTRACE=1` for the current process so
that we see backtraces when running in a terminal by default. This
should be fine but I just wanted to note it since it's a bit abnormal.
