Fixes another flack in the inlay hint cache.
Now that test does not fail after 500 iterations and seems to be stable
at last.

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.)

([#5098](https://github.com/zed-industries/zed/issues/5098)).

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

Release Notes:

- N/A

This PR updates the `HighlightedLabel` to correctly render its base
element, which is the one that receives the styling properties, instead
of rendering a new `LabelLike`.

Release Notes:

- N/A

Suppresses a flacky inlay hints test failures like
https://github.com/zed-industries/zed/actions/runs/7788741514a for now.

Release Notes:

- N/A

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.

- Added syntax highlighting for [Beancount](https://beancount.github.io)

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.

https://github.com/ash-rs/ash/issues/864

Hi folks! @absynce and I paired a bit to improve the
`elm-language-server` configuration. We have realised that sometimes
`elm-language-server` settings were being reset to default. We had been
configuring `elm-language-server` like this:

```json
"lsp": {
  "elm-language-server": {
    "initialization_options": {
      "disableElmLSDiagnostics": true,
      "onlyUpdateDiagnosticsOnSave": true,
      "elmReviewDiagnostics": "warning"
    }
  }
}
```

And then we noticed that the following communication happened:

```
// Send:
{"jsonrpc":"2.0","method":"workspace/didChangeConfiguration","params":{"settings":{}}}
// Receive:
{"jsonrpc":"2.0","id":5,"method":"workspace/configuration","params":{"items":[{"section":"elmLS"}]}}
// Send:
{"jsonrpc":"2.0","id":5,"result":[null],"error":null}
```

In `elm-language-server` the settings from `didChangeConfiguration`
[replace the initial
settings](https://github.com/elm-tooling/elm-language-server/blob/edd68133883f3902f8940a6e5e2834a9cd627dc1/src/common/providers/diagnostics/diagnosticsProvider.ts#L188).
Setting the value to `{}` effectively resets the configuration options
to defaults.

In Zed, `initialization_options` and `workspace_configuration` are two
different things, but in `elm-language-server` they are coupled.
Additionally, `elm-language-server` is requesting workspace
configuration for the `elmLS` section that doesn't exist.

This PR: 

1. Fixes settings reset on `didChangeConfiguration` by populating
`workspace_configuration` from `initialization_options`
2. Makes workspace configuration requests work by inserting an extra
copy of the settings under the `elmLS` key in `workspace_configuration`
— this is a bit ugly, but we're not sure how to make both kinds of
configuration messages work in the current setup.

This is how communication looks like after the proposed changes:

```
// Send:
{
  "jsonrpc": "2.0",
  "method": "workspace/didChangeConfiguration",
  "params": {
    "settings": {
      "disableElmLSDiagnostics": true,
      "onlyUpdateDiagnosticsOnSave": true,
      "elmReviewDiagnostics": "warning",
      "elmLS": {
        "disableElmLSDiagnostics": true,
        "onlyUpdateDiagnosticsOnSave": true,
        "elmReviewDiagnostics": "warning"
      }
    }
  }
}
// Receive:
{
  "jsonrpc": "2.0",
  "id": 4,
  "method": "workspace/configuration",
  "params": {
    "items": [
      {
        "section": "elmLS"
      }
    ]
  }
}
// Send:
{
  "jsonrpc": "2.0",
  "id": 4,
  "result": [
    {
      "disableElmLSDiagnostics": true,
      "onlyUpdateDiagnosticsOnSave": true,
      "elmReviewDiagnostics": "warning"
    }
  ],
  "error": null
}
```

Things we have considered:

1. Extracting the `elm-language-server` settings into a separate
section: we haven't found this being widely used in Zed, seems that all
language server configuration should fall under the top level `lsp`
section
2. Changing the way `elm-language-server` configuration works:
`elm-language-server` has got integrations with multiple editors,
changing the configuration behaviour would mean updating all the
existing integrations. Plus we are not exactly sure if it's doing
anything wrong.

Release Notes:

- Improved elm-language-server configuration options

This re-introduces the changes of #7305 but this time we create a
display link using the `NSScreen` associated with the window. We're
hoping we'll get these frame requests more reliably, and this seems
supported by the fact that awakening my laptop restores the frame
requests.

Release Notes:

- See #7305.

Adds settings for hiding breadcrumbs and quick action bar from
the editor toolbar. If both elements are hidden, the toolbar disappears
completely.

Example:

```json
"toolbar": {
  "breadcrumbs": true,
  "quick_actions": false
}
```

- It intentionally doesn't hide breadcrumbs in other views (for
instance, in the search result window) because their usage there differ
from the main editor.
- The editor controls how breadcrumbs are displayed in the toolbar, so
implementation differs a bit for breadcrumbs and quick actions bar.

Release Notes:

- Added support for configuring the editor toolbar ([4756](https://github.com/zed-industries/zed/issues/4756))

Closes #7288
