### 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.

You can now drag-and-drop on the remaining space in the project panel to
drop entries/external paths in the last worktree.
https://github.com/user-attachments/assets/a7e14518-6065-4b0f-ba2c-823c70f154f4
Release Notes:
- Added support for drag-and-drop files and external paths into the
empty space of the project panel, placing them in the last folder you
have added to the project.
A very primitive attempt, we just key the editor with the locations and
re-use the editor if we open a new buffer with the same initial
locations and title.
Release Notes:
- Added reusing of reference search buffers when applicable

Closes#36491
This issue is caused by the Python language configuration treating
compound statements (such as for loops and if statements) that end with
an inline comment as not requiring an increased indent.
Release Notes:
- python: Correctly indent lines starting the blocks (for, finally, if,
else, try) that have trailing comments.
This fixes a minor issue where we would show "Removing extension ..." in
the status bar when we would actually be installing it.
Release Notes:
- Fixed an issue where installing a dev extension would show the
installation status as "removing" in the activity indicator.
Closes#37980
There seems to be no reason to hard limit this to 1, and we even have
existing UX for this case already:

(Notice the different arrows in the gutter area for single lines)
Hence, allowing the value to honor the request from the issue
Release Notes:
- Allowed `0` as a value for the `excerpt_context_lines` setting
Closes#35623
Previously if a base keymap had a `null` set to an action, leading to a
`NoAction` being assigned to the keymap, if a user wanted to take
advantage of that keymap (in this particular case, `cmd-2`), the keymap
binding check would favor the `NoAction` over the user, since
technically the context depth matched better. Instead, we should always
prefer the user's settings over whatever base or default.
Release Notes:
- Fixed keymap precedence by favoring user settings over base keymap /
configs.
This PR moves the feature flag definitions to their own module so that

Closes #ISSUE
Adds handling for Enums with fields (i.e. not `enum Foo { Yes, No }`) in
Settings UI. Accomplished by creating default values for each element
with fields (in the derive macro), and rendering a toggle button group
with a button for each variant where switching the active variant sets
the value in the settings JSON to the default for the new active
variant.

## Context
While looking into: #32051 and #16120 with instruments, I noticed that
`TabSnapshot::to_tab_point` and `TabSnapshot::to_fold_point` are a
common bottleneck between the two issues. This PR takes the first steps
into closing the stated issues by improving the performance of both
those functions.
### Method
`to_tab_point` and `to_fold_point` iterate through each character in
their rows to find tab characters and translate those characters into
their respective transformations. This PR changes this iteration to take
advantage of the tab character bitmap in the `Rope` data structure and
goes directly to each tab character when iterating.
The tab bitmap is now passed from each layer in-between the `Rope` to
the `TabMap`.
### Testing
I added several randomized tests to ensure that the new `to_tab_point`
and `to_fold_point` functions have the same behavior as the old methods
they're replacing. I also added `test_random_chunk_bitmap` on each layer
the tab bitmap is passed up to the `TabMap` to make sure that the bitmap
being passed is transformed correctly between the layers of
`DisplayMap`.
`test_random_chunk_bitmap` was added to these layers:
- buffer
- multi buffer
- custom_highlights
- inlay_map
- fold_map
## Benchmarking
I setup benchmarks with criterion that is runnable via `cargo bench -p
editor --profile=release-fast`. When benchmarking I had my laptop
plugged in and did so from the terminal with a minimal amount of
processes running. I'm also on a m4 max
### Results
#### To Tab Point
Went from completing 6.8M iterations in 5s with an average time of
`736.13 ns` to `683.38 ns` which is a `-7.1875%` improvement
#### To Fold Point
Went from completing 6.8M iterations in 5s with an average time of
`736.55 ns` to `682.40 ns` which is a `-7.1659%` improvement
#### Editor render
Went from having an average render time of `62.561 µs` to `57.216 µs`
which is a `-8.8248%` improvement
#### Build Buffer with one long line
Went from having an average buffer build time of `3.2549 ms` to `3.2635
ms` which is a `+0.2151%` regression within the margin of error
#### Editor with 1000 multi cursor input
Went from having an average edit time of `133.05 ms` to `122.96 ms`
which is a `-7.5776%` improvement

Whilst looking into adding support for RainbowBrackes, we stumbled upon
this: Whereas for all properties during this blending, we take the value
of `other` if it is set, for the color we actually take `self.color`
instead of `other.color` if `self.color` is at full opacity.
`Hsla::blend` returns the latter color if it is at full opacity, which
seems wrong for this case. Hence, this PR swaps these.
Will not merge before the next release, to ensure that we don't break
something somewhere unexpected.
Release Notes:
- N/A
Previously we would still show a completion menu even when the user
typed an unrecognised mode with an argument,
e.g. `@something word`.
This PR ensures that we only show the completion menu, when the part
after the `@` is a known mode (e.g. `file`/`symbol`/`rule`/...)
Release Notes:
- Fix an issue where completions for `@mentions` in the agent panel
would sometimes not be dismissed when typing a space
TODO:
- [x] Double-check if we like the naming of the new actions
- [x] Only show keybinding hint once per option (e.g. if there are two
`allow_once` buttons only show it on the first one)
- [x] If there are multiple tool calls that need authorisation, only
show keybindings on the first tool call
- [x] Figure out which keybindings to use
- [x] Add linux keybindings
- [x] Add windows keybindings
- [x] Bug: long keybindings can make the buttons overflow
Release Notes:
- Add keybindings for authorizing tool calls (`agent: Allow once`,
`agent: Allow always`, `agent: Reject once`) in the agent panel
