This PR bumps the revision of the `livekit-rust-sdks` crate.

I was running into issue where Cargo was stuck on "Updating git
submodule `https://chromium.googlesource.com/libyuv/libyuv`".

I resolved the issue by forking `libyuv` to
https://github.com/zed-industries/libyuv and updating our
`livekit-rust-sdks` fork to use it in
https://github.com/zed-industries/livekit-rust-sdks/pull/4.

We'll now prompt the user to start a new thread when the active one gets
too long.

When they click "Start New Thread", will create a new one with the
previous one added as context.

Instead of including the full thread text, we'll now add summarized
versions of threads to the context, allowing you to continue the
conversation even if it was near the token limit.

- Thread summaries are cached and persisted. 
- A cached summary is invalidated if the thread is continued.
- We start generating the thread summary as soon as it's selected from
the picker. Most times, the summary will be ready by the time the user
sends the message.
- If the summary isn't ready by the time a message is sent, the user
message will be displayed in the thread immediately, and a "Summarizing
context..." indicator will appear. After the summaries are ready, we'll
start generating the response and show the usual "Generating..."
indicator.

Closes #20391

### Summary
This adds a persistence layer to the command palette so that usages can
persist after Zed is closed and re-opened.

The current "usage" algorithm is unchanged, e.g.:
- Sorts by number of usages descending (no recency preference)
- Once a user's query is active, removes these suggestions in favor of
fuzzy matching

There are some additional considerations in order to keep the DB from
growing uncontrollably (and to make long-term use ergonomic):
- The "invocations" count handles max values (though at u16, it seems
unlikely a user will deal with this)
- If a command is un-invoked for more than a month, it stops being
considered a recent usage, and its next update will update its usages
back to 1

### Future Considerations
- Could make the "command expiry" configurable in settings, so the user
can decide how long to hold onto recent usages
- Could make a more sophisticated algorithm which balances recency and
total invocations - e.g. if I've used COMMAND_A 100 times in the last
month, but COMMAND_B 10 times today, should COMMAND_B actually be
preferred?
- Could do preferential fuzzy-matching against these matches once the
user starts a query.

Release Notes:

- Added persistent history of command palette usages.

This PR adds some affordances for when the currently-selected model does
not support tools.

We disable the profile selector and put it into a "No Tools" state:

supports it.

Closes https://github.com/zed-industries/zed/issues/27619

Fixes issue with right wrapped movement when a multi-byte character is
at the end of the line. This is done by grabbing the last character on
the current row and using that characters size to calculate the
`max_column` variable, which is used to decide if the next right
movement should move down the line or not.

We did notice a bit of code that could be an issue that we wanted to
call out.
[Here](https://github.com/zed-industries/zed/blob/main/crates/editor/src/display_map.rs#L1070)
inside of `clip_at_line_end` it also does a saturating_sub(1), assuming
a single byte character. We didn't run into any issues due to this line
but felt like a similar bug. We can apply a similar fix if wanted to
pose the question first.

Test case: Moving to next line when eol is a multi-byte character

- Fixed issue in vim forward spacing when a multi-byte character is at

Python envs created with virtualenvwrapper have the ability to link to
the project directory (via the `.project` file in the virtualenv).
`python-environment-tools` supports this and reports the project path.

Additionally, some tools (e.g virtualfish) recognize special
"environment activation" files in project directories (`.venv` by
default)
[1].

Use the above information to sort reported Python toolchains so that the
correct env for a given worktree is at the top.

Closes #26902

- We used to serialize SSH remote only when opened via recent entries,
and not on first time. This broke restore, when opening same folder for
second time from recent entries. Once opened for second time, restoring
used to. work correctly. This PR fixes this by serializing when opened
for first time.

- We didn't handle window replace post worktree creation in first time
flow, this resulted in project panel not opening automatically like it
does with recent entries, or local projects. This PR fixes it by
following same flow as recent entries.

Release Notes:

- Fixed SSH remote not restoring when opening for second time.

This PR fixes two bugs that cause unexpected behavior with breakpoints.

The first bug made it impossible to delete the last breakpoint in a file
in the workspace's database. This caused deleted breakpoints to remain
in the database and added to new projects.

The second bug was an edge case in the breakpoint context menu where
disabling/enabling a breakpoint would sometimes set a new breakpoint on
top of the old breakpoint.
