Closes #40359

We were segfaulting when opening a UTF-8 file starting with a byte order
mark due to a mismatch in our UTF-16 indexing calculations caused by
Core Foundations `replace_str` stripping the BOM internally. This PR
fixes the crash by replacing one of our manual calculations by calling
the Core Foundations API to get the length of a string.

Release Notes:

- Fixed a crash on macOS when opening a file that starts with a UTF-8
byte order mark (BOM).

Fixes ZED-28R

Release Notes:

- Fixed open path prompt panicking on certain inputs

The `vim::visual::Vim.visual_block_motion` method was recently updated
(https://github.com/zed-industries/zed/pull/39355) in order to jump
between buffer rows instead of display rows. However, with this now
being the case, the `break` condition was never met when the motion was
horizontal rather than vertical and soft wrapped lines were used. As
such, this commit udpates the condition to ensure it's always reached,
preventing the hanging from happening.

Release Notes:

- Fixed hang in Vim's visual block motions when updating selections

Following a conversation with the maintainer/owner of
kotlin-language-server, he recommended switching to the official
language server, which is better in many aspects and also more actively
maintained.

Release Notes:

- Made the official Kotlin Language Server the default language server
for Kotlin.

We were dropping the entities once we created the buffers, so the weak
entities could never be upgraded. This treats new locations we see the
same as we would for a read/write call and stores the entity so that we
can follow like we normally would.

Release Notes:

- acp: Fix following not working with certain tool calls.

This fixes an issue where we would search for the hovered diff hunk
based on the mouse hit test computed during (or prior) editor paint
instead of the mouse hit test computed prior to the mouse event
invocation.

That in turn could lead to cases where moving the mouse from the editor
to the project panel and then clicking a file shortly after would expand
a diff hunk when actually nothing should happen in that case.

Release Notes:

- Fixed an issue where diff hunks would sometimes erroneously toggle
upon mouse clicks.

This feels a bit dangerous as long as we have the split releases problem

Updates #40212

v0.9.0 is now stable and contains the fix for the line endings bug, so
we can return to installing from the stable channel as usual. This also
bumps the minimum version on Windows to v0.9.0 so that anyone on v0.8.x
or v0.9.0-preview.4 will be upgraded automatically.

Closes #40334

This reverts the change made in #39983, and includes a replacement
migration that will transform formatter settings values consisting of
only `code_action` format steps into the previously deprecated
`code_actions_on_format` in an attempt to restore the behavior to what
it was before the migration that deprecated `code_actions_on_format`.

This PR will result in a modified order in the `code_actions_on_format`
setting if it existed, however the decision was made to explicitly
ignore this for now, as this PR is primarily targeting users who have
already had the deprecation migration run, and no longer have the
`code_actions_on_format` key

Release Notes:

- Fixed an issue with a settings migration that deprecated the
`code_actions_on_format` setting. The `code_actions_on_format` setting
has been un-deprecated, and affected users will have the bad migration
rolled back with an updated migration

We've been seeing the occasional `cannot seek backwards` panic within
`SelectionsCollection` without means to reproduce.

I believe the cause is one of the callers of
`MutableSelectionsCollection::select` not passing a well formed
`Selection` where `start > end`, so this PR enforces the invariant in
`select` by swapping the fields and setting `reversed` as required as
the other mutator functions already do that as well.

We could also just assert this instead, but it callers usually won't
care about this so its the less user facing annoyance to just fix this
invariant up internally.

We automatically delete a local workspace if the folders comprising it
no longer exist.
If a local workspace points to folders in the WSL filesystem, checking
whether those folders exist will make us wait for the WSL VM and file
server to boot up. This can block Zed startup for many seconds.

Supported scenarios use remote workspaces, so delete these local
workspaces to ensure that we don't try to access their folders on the
startup path.

Retrieval stats will now use polars to build a big data frame for
references with the cartesian product of LSP declarations and retrieved
declaration candidates (with all their score components) and rebuilds
the stats summary on top of it.

This data frame is written to a `.parquet` file, which we can load into
advanced analytics tools (such as Metabase), so we can explore our
scoring distributions and find ways to improve retrieval, and then train
the decision tree.

Added a "Copy All Messages" button to the ACP logs toolbar that copies
all messages in the watched stream to the clipboard as structured JSON.

## Motivation

When troubleshooting ACP protocol implementations, it's helpful to
provide the entire message thread to an LLM for analysis. Previously, I
had to copy individual messages one at a time, which was tedious and
time-consuming. This feature allows copying the entire conversation
history in a single click.

Release Notes:

- Added: Copy All Messages button to ACP logs view
