Calling `Rope::chars` got slightly slower but I don't think it's a big
issue (we don't really call `chars` for an entire `Rope`).

In a future pull request, I want to use the tab index (which we're not
yet using) and the char index to make `TabMap` a lot faster.

This PR changes the way we load user themes into the ThemeRegistry. 

Rather than directly pass a theme family's themes to
`insert_user_themes`, instead we use the new `refine_theme_family ` and
`ThemeFamily::refine_theme`.

This PR should have net zero change to themes today, but sets up
enabling theme variables. We need to do it this way so each theme has
access to it's family when it is refined.

As we don't use scrolling flex layouts directly in panes that often, the
methods that would normally be applied to containers that should fill
the space weren't applied here.

Should help un-stuck #19872's layout issue, but I'm merging this change
separately in case it creates some other layout issue in panes.

This PR improves the parsing of Git remote URLs in order to make
features that depend on them more robust.

Previously we were just treating these as plain strings and doing
one-off shotgun parsing to massage them into the right format. This
meant that we weren't accounting for edge cases in URL structure.

One of these cases was HTTPS Git URLs containing a username, which can
arise when using GitHub Enterprise (see
https://github.com/zed-industries/zed/issues/11160).

We now have a `RemoteUrl` typed to represent a parsed Git remote URL and
use the `Url` parser to parse it.

Release Notes:

- Improved the parsing of Git remote URLs to support additional
scenarios.

This is the start of a notebook UI for Zed. 

`🔔 Note: This won't be useable yet when it is merged! Read below. 🔔`

This is going to be behind a feature flag so that we can merge this
initial PR and then make follow up PRs. Release notes will be produced
in a future PR.

Minimum checklist for merging this:

* [x] All functionality behind the `notebooks` feature flag (with env
var opt out)
* [x] Open notebook files in the workspace
* [x] Remove the "Open Notebook" button from title bar
* [x] Incorporate text style refinements for cell editors
* [x] Rely on `nbformat` crate for parsing the notebook into our
in-memory format
* [x] Move notebook to a `gpui::List`
* [x] Hook up output rendering

Release Notes:

- Fixed a bug where the Julia icon was not displayed for Julia files.

This a separate PR from https://github.com/zed-industries/zed/pull/19705
so we can revert it more easily if we want it back later.

Release Notes:

- Added "Suggest Edit" button to the assistant panel if
`"enable_experimental_live_diffs": true` is set in the `"assistant"`
section of `settings.json`. This button takes the place of the previous
`/workflow` command, but it is experimental and may change!

This PR adds support for self-hosted GitLab instances when generating
Git permalinks.

If the `origin` Git remote contains `gitlab` in the URL hostname we will
then attempt to register it as a self-hosted GitLab instance.

A note on this: I don't think relying on specific keywords is going to
be a suitable long-term solution to detection. In reality the
self-hosted instance could be hosted anywhere (e.g.,
`vcs.my-company.com`), so we will ultimately need a way to have the user
indicate which Git provider they are using (perhaps via a setting).

Closes https://github.com/zed-industries/zed/issues/18012.

Release Notes:

- Added support for self-hosted GitLab instances when generating Git
permalinks.
- The instance URL must have `gitlab` somewhere in the host in order to
be recognized.

Previously, when scrolling the diagnostics view with the mouse, we'd get
a spurious horizontal scroll (even if the content was not overflowing
horizontally) due to an error in the widths of the diagnostic blocks.

Release Notes:

- Fixed an issue where the project diagnostics view spuriously allowed
horizontal scrolling by a small amount.

Release Notes:

- Linux: Now skips check which exits with "zed is already running" when
in development mode or when run with `zed-local`, matching the behavior
on Mac and Windows

but for ssh project the `replica_id` is actually `1`.

Trying to quantify a performance impact, it doesn't seem to impact much

We're still taking a few hundred micro-seconds (+/- a lot) every time.
The ascii file has just ascii, where as the cc file has one control
character per line.

Why manual recursion?
- Due to tree-sitter grammar not supporting recursion in query
(https://github.com/tree-sitter-grammars/tree-sitter-lua/issues/24),
currently only manual recursion is possible (refer to
https://github.com/projekt0n/github-nvim-theme/pull/250/files).

<br/>

Unable to highlight when simple structures appear before complex
structures, example:
```python
def t() -> str | dict[int, dict[int, dict[int, str]]]:
    pass
```
Because complex structures are parsed as `subscript` rather than
`generic_type` by tree-sitter in this case ☹

Release Notes:

Also change Zed's standard style to use
`.track_focus(&self.focus_handle(cx))`, instead of
`.track_focus(&self.focus_handle)`, to catch these kinds of errors more
easily in the future.
