Improve docs & remove `vulkan-validation-layers` from the dependencies.

Release Notes:

- Fixed a panic in the assistant panel when the app is shutting down.

The current gutter was a bit too big for my taste, so I added some
settings to change which visual elements are shown, including being able
to hide the gutter completely.

This should help with the following issues: #4963, #4382, #7422

New settings:
```json5
"gutter": {
    "line_numbers": true, // Whether line numbers are shown
    "buttons": true // Whether the code action/folding buttons are shown
}
```

The existing `git.git_gutter` setting is also taken into account when
calculating the width of the gutter.

We could also separate the display of the code action and folding
buttons into separate settings, let me know if that is desirable.

## Screenshots:

- Everything on (`gutter.line_numbers`, `gutter.buttons`,
`git.git_gutter`):

This PR adds a `SystemClock` trait for abstracting away the system
clock.

This allows us to swap out the real system clock with a
`FakeSystemClock` in the tests, thus allowing the fake passage of time.

We're using this in `Telemetry` to better mock the clock for testing
purposes.

[Profiling](https://crates.io/crates/profiling) crate allows easy
integration with various profiler tools. The best thing is - annotations
compile to nothing unless you request a specific feature.

For example, I used this command to enable Tracy support:
```bash
cargo run --features profiling/profile-with-tracy
```
At the same time I had Tracy tool open and waiting for connection. It
gathered nice stats from the run:

I really think storybook is a cool standalone app but there are some
usability issues that are getting in the way of making this a fun tool
to use.

Currently it is not easy to gracefully exit out of storybook.

In fact even trying to Ctrl-c out of storybook seems currently broken to
me...

So the only real way to exit out of storybook is to kill the process
after a Ctrl-z.

This PR attempts to make this much easier by adding a simple app_menu
with a menu item called quit along with the ability to *Cmd-q* out of
storybook as well...

Both the menu item quit and *Cmd-q* gracefully exit storybook.

There are still a bunch of issues with storybook which I plan on
addressing in future PR's but this is a start and something that to me
is the highest priority to make storybook more functional and easy to
use moving forward.

One of my longer term goals of storybook is to have it be a nice stand
alone application similar to
[Loungy](https://github.com/MatthiasGrandl/Loungy) which can be used as
a nice tutorial application for how to develop a real world *gpui* app.

For that reason I added a *assets/keymaps/storybook.json* file as well.

Implements keyboard focus in/out events.

This also enables vim mode to work on wayland, which is only activated
when an editor gains focus.

Fixes 'Reveal in Finder' opening files instead of showing them in the
file explorer.
Tested on Fedora KDE 39.

Release Notes:

- N/A

Fix an issue where the `ime_key` is sometimes an empty string, and
pressing a keystroke replaces the selected text.

E.g. select some text, press `Escape`: selected text is deleted.

This PR adds a checkbox to the extensions view to allow filtering to
just extensions that are installed:

Release Notes:

- Added a checkbox to the extensions view to only show installed
extensions.

Release Notes:

- vim: Added a setting to control default clipboard behaviour. `{"vim":
{"use_system_clipboard": "never"}}` disables writing to the clipboard.
`"on_yank"` writes to the system clipboard only on yank, and `"always"`
preserves the current behavior. ([#4390

I ran into this when trying out which keybindings work and accidentally
added empty tasks. They get then added to the task inventory and
displayed in the picker.

- Fixed empty tasks being added to the list of tasks when using `task:
spawn`

zed.dev PR: https://github.com/zed-industries/zed.dev/pull/562

I've been wanting to be able to open release notes in Zed for awhile,
but was blocked on having a rendered Markdown view. Now that that is
mostly there, I think we can add this. I have not removed the `auto
update: view release notes` action, since the Markdown render view
doesn't support displaying media yet. I've opted to just add a new
action: `auto update: view release notes locally`. I'd imagine that in
the future, once the rendered view supports media, we could remove `view
release notes` and `view release notes locally` could replace it.
Clicking the toast that normally is presented on update
(https://github.com/zed-industries/zed/issues/7597) would show the notes
locally.

The action works for stable and preview as expected; for dev and
nightly, it just pulls the latest stable, for testing purposes.

I changed the way the markdown rendered view works by allowing a tab
description to be passed in.

For files that have a name, it will use `Preview <name>`:

For untitled files, it defaults back to `Markdown preview`:

We have to pass a name there too, but the problem here is that the

slightly.

Fixes #8096

# Bug description

I was experimenting with adding extensions and almost went crazy trying
to make my demo extension work. It appeared that I was copying files
with Finder that creates hidden `.DS_Store` files which interfered with
Zed's loading logic. It assumes that `languages/` directory contains
only directories and never files and so it crashes when meets
`.DS_Store`. This makes any extension stop working after it has been
viewed via Finder

# Change

Check if path is directory when loading extension languages (so it will
skip .DS_Store files)

Added documentation for
[#4970](https://github.com/zed-industries/zed/issues/4970), a feature
added in the latest update. Will need to modify `Default Settings` to
reflect the new default theme example.

In #6954 a user has trouble using copilot. We haven't gotten to the
bottom of the problem, but one problem is that apparently sometimes (I'm
going to find out when) copilot sends an `"OK"` status message without a
username. This is from the user's logs:

2024-02-20T15:28:41-03:00 [ERROR] failed to deserialize response from
language server: missing field `user`. Response from language server:
"{\"status\":\"OK\"}"

The official `copilot.vim` plugin handles this as if the user is not
authenticated (!= authorized):


https://github.com/github/copilot.vim/blob/1a284014d2e0baf367706a94b2a9ee5fd56fd457/autoload/copilot.vim#L574-L579

So that's what I'm doing here too.
