Closes #21305

As Linux doesn’t have native prompts, Zed uses a custom GPU-based
prompt, like the "About Zed" prompt. Currently, the detail in the prompt
isn’t selectable.

This PR fixes that by using the editor's multi-line selectable
functionality to make the detail selectable (and thus copyable). It
achieves this by disabling editing and setting the cursor to
transparent. The editor also does all the heavy lifting, like
double-clicking to select a word or triple-clicking to select a line,
like what user expects from selectable.

Follow up to https://github.com/zed-industries/zed/pull/21593

This PR updates all built-in themes `panel.focused_border` tokens using
the same HEX code used for `text_accent`.

There shouldn't be any visual change here given the project panel item,
when focused, was using `Color::Selected`, which maps to `text_accent`,
to color its border. In the linked PR above, the project panel item was
updated to use the dedicated token for that. This is good because now
theme markers will be able to customize them separately (e.g., having a
different `text_accent` color than `panel.focused_border`).

version 1.5.5

Changes since 1.5.4:

-   `b3sum --check` now supports checkfiles with Windows-style newlines.
    `b3sum` still emits Unix-style newlines, even on Windows, but
    sometimes text editors or version control tools will swap them.
-   The "digest" feature (deleted in v1.5.2) has been added back to the
    `blake3` crate. This is for backwards compatibility only, and it's
    insta-deprecated. All callers should prefer the "traits-preview"
    feature.

This PR makes the border color of a focused project panel item use the
`panel_focused_border` theme token. This allow theme makers to customize
that independently of the `text_accent` color, which was the one being
previously used.

I added some shortcuts that I believe will be helpful for most users. I
tried to keep the default key mappings for the shortcuts inline with
Zed's vim mode.

Closes #21576

This issue is caused by the fuzzy matching for snippets I added
[here](https://github.com/zed-industries/zed/pull/21524). When
encountering symbols such as `:`, `(`, `.`, etc., the `last_word`
becomes empty, which results in an empty string being passed to
`fuzzy_match`, leading to the return of all templates.

This fix adds an early return when `last_word` is empty.

This is a pure refactor of our Git diff state management. Buffers are no
longer are associated with one single diff (the unstaged changes).
Instead, there is an explicit project API for retrieving a buffer's
unstaged changes, and the `Editor` view layer is responsible for
choosing what diff to associate with a buffer.

The reason for this change is that we'll soon want to add multiple "git
diff views" to Zed, one of which will show the *uncommitted* changes for
a buffer. But that view will need to co-exist with other views of the
same buffer, which may want to show the unstaged changes.

### Todo

* [x] Get git gutter and git hunks working with new structure
* [x] Update editor tests to use new APIs
* [x] Update buffer tests
* [x] Restructure remoting/collab protocol
* [x] Update assertions about staged text in
`random_project_collaboration_tests`
* [x] Move buffer tests for git diff management to a new spot, using the
new APIs

Technically, this is an LSP violation from `vtsls`, but seems that it's
not going to be fixed adequately on that side, see
https://github.com/yioneko/vtsls/issues/213 for more context.
So, we have to accommodate at least for now.

Release Notes:

- Fixed completion item labels not being updated after the resolve for
non-LSP compliant servers

Part of https://github.com/zed-industries/zed/issues/20925

This prototype is behind a feature flag and being merged to avoid
conflicts with further git-related resturctures.
To be a proper, public feature, this needs at least:
* showing deleted files
* better performance 
* randomized tests
* `TODO`s in the `project_diff.rs` file fixed

The good thing is, >90% of the changes are in the `project_diff.rs` file
only, have a basic test and already work on simple cases.
