This fixes #7401 and probably a few other things that seemed odd with
the terminal.

Turns out that `TerminalView` has `focus_in` and `focus_out` callbacks,
but they were never called. The `focus_handle` on which they were set
was not passed in to `TerminalView`.

That meant that the `impl FocusableView for TerminalView` never returned
the focus handle with the right callbacks.

This change here uses the already created focus handle and passes it in,
so that `focus_in` and `focus_out` are now correctly called.

Release Notes:

- Fixed terminal not handling focus-state correctly and, for example,
not restoring cursor blinking state correctly.
([#7401](https://github.com/zed-industries/zed/issues/7401)).

Before this change if you had joined a call with an empty workspace,
then we'd prompt you to hang up when you tried to open a recent project.



Release Notes:

- Fixed an erroneous prompt to "hang up" when opening a new project from
an empty workspace.

This PR is a follow-up from
https://github.com/zed-industries/zed/pull/6786#issuecomment-1912912550
and adds an `outline.scm` file for buffer symbol search support in
Haskell.

Release Notes:

- Added buffer symbol search support for Haskell

- Another broken following test
- Fix following between two windows

Release Notes:

- Fixed following when the leader has multiple Zed windows open

This PR adds support for configuring both a light and dark theme in
`settings.json`.

In addition to accepting just a theme name, the `theme` field now also
accepts an object in the following form:

```jsonc
{
  "theme": {
    "mode": "system",
    "light": "One Light",
    "dark": "One Dark"
  }
}
```

Both `light` and `dark` are required, and indicate which theme should be
used when the system is in light mode and dark mode, respectively.

The `mode` field is optional and indicates which theme should be used:
- `"system"` - Use the theme that corresponds to the system's
appearance.
- `"light"` - Use the theme indicated by the `light` field.
- `"dark"` - Use the theme indicated by the `dark` field.

Thank you to @Yesterday17 for taking a first stab at this in #6881!

Release Notes:

- Added support for configuring both a light and dark theme and
switching between them based on system preference.

Release Notes:

- Fixed terminal's copy to clipboard being non-instant ([7322](https://github.com/zed-industries/zed/issues/7322))

Terraform and HCL are almost the same language, but not quite so
proposing them as separate languages within Zed. (Terraform is an
extension of HCL, with a different formatter.)

This is just adding the language definition, parsing and highlighting
functionality, not any LSP or formatting beyond that for either
language.

I've taken a bunch of inspiration from Neovim for having the separate
languages, and also lifted some of their `scm` files (with attribution
comments in this codebase) as the tree-sitter repo doesn't contain them.
(Neovim's code is Apache-2.0 licensed, so should be fine here with
attribution from reading Zed's licenses files.) I've then amended to
make sure the capture groups are named for things Zed understands. I'd
love someone from Zed to confirm that's okay, or if I should clean-room
implement the `scm` files.

Highlighting in Terraform & HCL with a moderate amount of syntax in a
file (Terraform on left, HCL on right.)

This PR simplifies the removal of the file name from the file path when
computing the file finder matches.

This PR updates the `HighlightedLabel` to correctly render its base

of rendering a new `LabelLike`.

Suppresses a flacky inlay hints test failures like

Release Notes:

File finder looks and feels a little bulky now. It duplicates file names
and consumes too much space for each file.

This PR makes it more compact:
- File name is trimmed from the path, removing duplication
- Path is placed to the right of the file name, improving space usage
- Path is muted and printed in small size to not distract attention from
the main information (file names)

It makes search results easier to look through, consistent with the
editor tabs, and closer in terms of usage to mature editors.

Release Notes:

- File finder UI enhancement

Runs scheduled CI jobs only on the main repository, not on forks. These
jobs fail on forks and generate unnecessary noise on contributor emails.

This fixes `cmd+k` in the terminal taking 1s to have an effect. It is
now immediate.

It also fixes #7270 by ensuring that we don't set a bad state when
matching keybindings.

It matches keybindings per context and if it finds a match on a lower
context it doesn't keep pending keystrokes. If it finds two matches on
the same context level, requiring more keystrokes, then it waits.



Release Notes:

- Fixed `cmd-k` in terminal taking 1s to have an effect. Also fixed
sporadic non-matching of keybindings if there are overlapping
keybindings.
([#7270](https://github.com/zed-industries/zed/issues/7270)).

This PR populates the `search.match_background` colors in the bundled
themes, using the values from the Zed1 themes.

Release Notes:

- Added theme-specific `search.match_background` colors to built-in
themes.

Turns out that these keybindings are active in Vim *and* in non-Vim mode
and they shadow `Ctrl-w` in terminals.

We should fix `Ctrl-w` being shadowed, but until then let's remove the
default keybindings.

This PR improves the contrast of the default `search_match_background`
colors.

Release Notes:

- Improved the contrast of the default `search.match_background` colors.

Refactor the hint query code to pass along an actual `cx` instead of its
potentially stale, cloned version.

Release Notes:

- Fixed occasional duplicate hints inserted and offset-related panics
when concurrently editing the buffer and querying multiple its ranges
for hints

That way crates that use Picker::new do not have to codegen constructor of Editor; tl;dr, 10% of LLVM shaved off of crates like vcs_menu or theme_selector in release mode.

This fixes #7348 by not rendering completions if they are disabled in
the settings. Previously we only checked that setting when starting or
not starting background threads to fetch documentation. But in case we
already have documentation, this stops it from being rendered.

Release Notes:

- Fixed documentation in completions showing up even when disabled via
`show_completion_documentation`
([#7348](https://github.com/zed-industries/zed/issues/7348))

It allows us to receive messages from the dispatcher,
which breaks us out of waiting and lets us execute
main thread runnables as a part of the main loop.
