This PR updates the extension list to disable remote entries when the
corresponding dev extension is installed.

Here is what this looks like:

Release Notes:

- Disabled extension entries when there is a development copy of that
extension installed.

Fixes:  #10539

Release Notes:

- vim: Use `\<` `\>` instead of `\b`

Although we thought this fixed the bug, it just worked around it, and
runnign two copies of tracing in one app is a bad idea.

This PR makes it so clicking "Install" will install the latest
compatible version of an extension instead of disabling the button when
the latest version is not compatible.

The "Upgrade" button will still be disabled when the latest version is
not compatible. We will also now display a tooltip to better indicate
why the button is disabled:

Related to https://github.com/zed-industries/zed/issues/10509.

Release Notes:

- Changed the "Install" button for extensions to always install the
latest compatible version instead of becoming disabled when the latest
version of an extension is incompatible with the current Zed version.

This PR adds an indicator to show what extension version is currently
installed when on an extension version that is not the latest.

Release Notes:

- Added an indicator to show the currently-installed extension version
when not on the latest version.

This fixes an issue that could cause `from_iter` to never finish if the
underlying iterator restarted after returning `None` for the first time.

We only saw this in development but I wanna cherry-pick it to stable and
preview, just in case.

Here comes a lenghty explanation for a short commit: We've had feedback
that our diagnostics tab often mismatches what's shown in the status
bar. E.g: https://x.com/fasterthanlime/status/1778764747732594753 Let's
dive into the lifetime of diagnostic tab first; it is actually spawned
*just once per workspace*, the first time you click on the diagnostics
status indicator. Even if you close this tab, we still reuse the same
object under the hood later on. This has upsides, as it means that you
can close a tab and then reopen it with your selections still in-tact
and so on. However, this also leads to the perceived staleness.
Crucially, the first time ever in a given session that you spawn the
diagnostics tab, the status bar counts match the content of a tab. That
is because we always call \`update_excerpts\` when we create diagnostics
tab for the first time, but later on we have severe constraints on when
we want to update the excerpts in diagnostics tab, mostly centered
around presence of selections in an editor... but, since we reuse the
diagnostic tab object under the hood, we're always gonna have at least
one selection in an editor sans the first time you open it. The end
result is that in order for diagnostic tab contents to be updated, we
have to get a "on-disk-diagnostics-finished" notification from language
server, which can take a long time.
Another example of this property manifesting itself is that if you fix a
diagnostic warning/error, it takes a while for diagnostic tab to reflect
it.

With this PR, I've afforded a bit of leniency in refreshing the contents
of that tab. The old check that discarded updates when diagnostics
editor had at least one selection has been updated to instead reject
multicursors; this is still overly conservative, as I'm not yet sure how
big of an issue is the cursor that's jumping around (as that's what the
selections constraint is supposed to prevent).



Release Notes:

- Fixed diagnostics tab showing outdated entries before the language
server is done with it's analysis.

This fixes the problem of the Zig extension picking up `zls` from the
shell env but `zls` then failing to launch because it cannot find `zig`.

Scenario in which this happens:
- `.envrc` in a project that sets `$PATH` up
- in that `$PATH` there's `zls` and `zig`
- Zed is started from Dock
- Project is opened
- Shell env from project directory is loaded and used to get to `zls`
- `zls` is then started, without that environment set on the process
- `zls` cannot find `zig`

This fixes a bug that caused the editor to be rendered incorrectly when
its bounds extended outside the content mask. This is because the editor
uses the returned `Hitbox` bounds to determine the origin of its
elements.

With this commit, we will now store a new `content_mask` field within
the `Hitbox` struct which is captured when the hitbox is inserted. Then,
the content mask is applied on the fly when performing a hit test to
determine whether the hitbox is actually hovered.

Part of https://github.com/zed-industries/zed/issues/5141

* adds "run selection" and "run file" tasks for bash and Python.
* replaces newlines with `\n` symbols in the human-readable task labels
* properly escapes task command arguments when spawning the task in
terminal

Caveats:

* bash tasks will always use user's default shell to spawn the
selections, but they should rather respect the shebang line even if it's
not selected
* Python tasks will always use `python3` to spawn its tasks now, as
there's no proper mechanism in Zed to deal with different Python
executables

Release Notes:

- Added tasks for bash and Python to execute selections and open files
in terminal

Some people (like myself) use touchpads for development and I find Zed's
default scroll sensitivity to be slower than I like. This change adds a
scroll sensitivity multiplier that allows users to customize the speed
of their scrolling.

Release Notes:

- Added a setting under "scroll_sensitivity" that allows user to control
the scroll sensitivity. This value acts as a multiplier for the
horizontal and vertical scroll speed.

This adds so-called "inline git blame" to the editor that, when turned
on, shows `git blame` information about the current line inline:


![screenshot-2024-04-15-11 29
35@2x](https://github.com/zed-industries/zed/assets/1185253/21cef7be-3283-4556-a9f0-cc349c4e1d75)


When the inline information is hovered, a new tooltip appears that
contains more information on the current commit:


![screenshot-2024-04-15-11 28
24@2x](https://github.com/zed-industries/zed/assets/1185253/ee128460-f6a2-48c2-a70d-e03ff90a737f)

The commit message in this tooltip is rendered as Markdown, is
scrollable and clickable.

The tooltip is now also the tooltip used in the gutter:

![screenshot-2024-04-15-11 28
51@2x](https://github.com/zed-industries/zed/assets/1185253/42be3d63-91d0-4936-8183-570e024beabe)


## Settings

1. The inline git blame information can be turned on and off via
settings:
```json
{
  "git": {
    "inline_blame": {
      "enabled": true
    }
  }
}
```
2. Optionally, a delay can be configured. When a delay is set, the
inline blame information will only show up `x milliseconds` after a
cursor movement:
```json
{
  "git": {
    "inline_blame": {
      "enabled": true,
      "delay_ms": 600
    }
  }
}
```
3. It can also be turned on/off for the current buffer with `editor:
toggle git blame inline`.

## To be done in follow-up PRs

- [ ] Add link to pull request in tooltip
- [ ] Add avatars of users if possible

## Release notes

Release Notes:

- Added inline `git blame` information the editor. It can be turned on
in the settings with `{"git": { "inline_blame": "on" } }` for every
buffer or, temporarily for the current buffer, with `editor: toggle git
blame inline`.

Before, `tasks_ui` set most of the context with `SymbolContextProvider`
providing the symbol data part of the context. Now, there's a
`BasicContextProvider` that forms all standard Zed context and it
automatically serves as a base, with no need for other providers like
`RustContextProvider` to call it as before.

Also, stop adding `SelectedText` task variable into the context for
blank text selection.

This PR adjusts our scrolling implementation to delay the generation of
ScrollWheel events until we receive a complete frame.

Note that our implementation is still a bit off-spec, as we don't delay
any other kind of events. But it's been working so far on a variety of
compositors and the other events contain complete data; so I'll hold off
on that refactor for now.

This introduces semantic indexing in Zed based on chunking text from
files in the developer's workspace and creating vector embeddings using
an embedding model. As part of this, we've created an embeddings
provider trait that allows us to work with OpenAI, a local Ollama model,
or a Zed hosted embedding.

The semantic index is built by breaking down text for known
(programming) languages into manageable chunks that are smaller than the
max token size. Each chunk is then fed to a language model to create a
high dimensional vector which is then normalized to a unit vector to
allow fast comparison with other vectors with a simple dot product.
Alongside the vector, we store the path of the file and the range within
the document where the vector was sourced from.

Zed will soon grok contextual similarity across different text snippets,
allowing for natural language search beyond keyword matching. This is
being put together both for human-based search as well as providing
results to Large Language Models to allow them to refine how they help
developers.

Remaining todo:

* [x] Change `provider` to `model` within the zed hosted embeddings
database (as its currently a combo of the provider and the model in one
name)
