Exposes a new "edit files" tool that the model can use to apply
modifications to files in the project. The main model provides
instructions and the tool uses a separate "editor" model (Claude 3.5 by
default) to generate search/replace blocks like Aider does:

````markdown
mathweb/flask/app.py
```python
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
````

The search/replace blocks are parsed and applied as they stream in. If a
block fails to parse, the tool will apply the other edits and report an
error pointing to the part of the input where it occurred. This should
allow the model to fix it.

# Issue
### Related issues:
* https://github.com/zed-industries/zed/issues/26393
* https://github.com/zed-industries/zed/issues/11043

When you try to copy a permalink from a self-hosted GitHub enterprise
instance, you get the following error:

<img width="383" alt="permalink"
src="https://github.com/user-attachments/assets/b32338a7-a2d7-48fc-86bf-ade1d32ed1f7"
/>

You also cannot open a PR or commit when you hover over a git blame:


https://github.com/user-attachments/assets/a5491ce7-270b-412f-b9ac-027ec020b028


### Reproduce
If you do not have access to a self-hosted GitHub instance, you can
change the remote url of any git repo:
```
git remote set-url origin git@github.mycorp.com:nilskch/zed.git
```

With the fix, permalinks still won't bring you to a valid website, but
you can verify that they are correctly created.

# Solution

Currently, we only support detecting self-hosted GitLab instances, but
not self-hosted GitHub instances. We detect GitLab instances by checking
if "gitlab" is part of the git URL.

This PR adds the same logic to detect self-hosted GitHub enterprise
instances (by checking if "github" is in the URL).

This solution is not ideal, since self-hosted GitHub or GitLab instances
might not contain the word "github" or "gitlab". #26393 proposes adding
a setting that would allow users to map specific domains to their
corresponding git provider types. This mapping would help Zed correctly
identify the appropriate git instance, even if "gitlab" or "github" are
not part of the URL.

This PR does not implement the offered solution, but I added a TODO
where the fix for #26393 has to make changes.

Previously, when a file was deleted externally and the warning prompt
was dismissed with "Close", the panel remained but was empty, leaving an
unused split space.

This happened because pane.remove_item(...) was being called with
close_pane_if_empty set to false, preventing the panel from being
removed even when it had no remaining items.

This fix changes the third boolean parameter to true, ensuring that the
panel is removed if it becomes empty, allowing the layout to properly
resize.

Closes #23904

Known Issues:
- When items can horizontal scroll, the right selected border is hidden

TODO:
- [ ] Width calculation is off
- [ ] When scrollbars should autohide they don't until hovering the
panel
- [ ] When switching to and from scrollbar track being visible we are
missing a notify somewhere.

Release Notes:

- Git Panel: Added horizontal scrolling in the git panel

- Git Beta: Fixed a bug where our push button would always overwrite the
current branch's upstream

This PR fixes a long repo name pushing the branch selector off the
screen, as well as just generally truncating them down in a way smarter
than a fixed character limit when long.

Release Notes:

- Git Panel: Smart truncate long branch and repository names in their
respective selectors

This PR removes the "Tools" switch from Assistant 2, as we can manage
tools from the tool selector now.

Release Notes:

- N/A

The notifications from git output could take up variable amounts of
screen space, and they were quite obnoxious when a git command printed
lots of output, such as fetching many new branches or verbose push
hooks.

This change makes the push/pull/fetch buttons trigger a small
notification toast, based on the output of the command that was ran. For
errors or commands with more output the user may want to see, there's an
"Open Log" button which opens a new buffer with the output of that
command.

It also uses this behavior for long error notifications for other git
commands like `commit` and `checkout`. The output of those commands can
be quite long due to arbitrary githooks running.

Currently, macOS doesn't support showing multi-keystroke shortcuts in

that breaks consistency with traditional shortcuts.

This PR makes `io.open` use our own implementation again, but instead of
the real filesystem, it will now use the project's to check file
metadata and perform read and writes using project buffers.

multiple methods, adds tests for various File I/O patterns, and fixes a
few bugs in read formats.
