This PR changes our approach to initializing the `SystemAppearance` so
that we can do it earlier in the startup process.

Previously we were using the appearance from the window, meaning that we
couldn't initialize the value until we first opened the window.

Now we read the `window_appearance` from the `AppContext`. On macOS this
is backed by the
[`effectiveAppearance`](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance)
on the `NSApplication`.

We currently still watch for changes to the appearance at the window
level, as the only hook I could find in the documentation is
[`viewDidChangeEffectiveAppearance`](https://developer.apple.com/documentation/appkit/nsview/2977088-viewdidchangeeffectiveappearance),
which is at the `NSView` level.

In my testing this makes it so Zed appropriately chooses the correct
light/dark theme on startup.

This would regress performance because we'd be using the standard
library's hash maps everywhere, so reverting for now.

This highlights dead keys. Example: when in Brazilian keyboard layout
and typing `"` it's now underlined.

Previously it wasn't possible to create a keybinding for this action
because it required an argument.

Now the action takes the active item of the pane and if it's a
multi-buffer the first one.

This also adds a default keybinding for Vim mode: `-` will reveal the
file in the project panel.

Fixes #7485.

Release Notes:

- Added `pane::RevealInProjectPanel` as an action in the command
palette. ([#7485](https://github.com/zed-industries/zed/issues/7485)).

This was originally just to fix
https://github.com/zed-industries/zed/issues/4354, which I did by just
returning the previous offset in `find_boundary`.. but `find_boundary`
is used in the "insert mode" / normal editor too, so returning the
previous boundary breaks existing functionality in that case.

I was considering a new `find_boundary` function just for some of the
vim motions like this, but I thought that this is straightforward enough
and future Vim functions might need similar logic too.

Release Notes:

- Fixed https://github.com/zed-industries/zed/issues/4354

Fixes: #2750
Fixes: #7457



Release Notes:

- Fixed a hang/panic that could happen rendering a double-width
character in a single-width terminal
([#2750](https://github.com/zed-industries/zed/issues/2750),
[#7457](https://github.com/zed-industries/zed/issues/7457)).

We noticed the following message in my logs when trying to debug some
lag when collaborating:

```
2024-02-06T09:42:09-08:00 [ERROR] error handling message. client_id:3, sender_id:Some(PeerId { owner_id: 327, id: 1123430 }), type:GetCompletions, error:no such connection: 0/0
```

That `0/0` looks like a bogus connection id, constructed via a derived
`Default`. We didn't ever find a code path that would *use* a default
`ConnectionId` and lead to this error, but it did seem like an
improvement to not have a `Default` for that type.

Turns out that Nushell doesn't like `-lic` and `&&`, but works perfectly
fine with `-l -i -c` and `;`, which the other shells do too.

These all work:

    bash -l -i -c 'echo lol; /usr/bin/env -0'
    nu -l -i -c 'echo lol; /usr/bin/env -0'
    zsh -l -i -c 'echo lol; /usr/bin/env -0'
    fish -l -i -c 'echo lol; /usr/bin/env -0'

Release Notes:

- Fixed shell environment not being loaded if Nushell was set as
`$SHELL`.

Tried to match the existing file icons in Zed as much as possible. This
is how it looks:

|  dark  | light  | 
|---|----|
| <img width="183" alt="Screenshot 2024-02-06 at 15 03 57"
src="https://github.com/zed-industries/zed/assets/43472/bd862753-41bb-4ca6-9a44-16b9b1c9591c">
| <img width="180" alt="Screenshot 2024-02-06 at 15 03 14"
src="https://github.com/zed-industries/zed/assets/43472/9df8c589-64b6-49f2-8e15-b43126579a9f">
|

The main challenge is that the tangram is visually quite heavy and
detailed. The existing icons in Zed are designed in a 14px bounding box,
but are a bit smaller themselves. I guess the extra space is reserved
for hanging elements, it probably doesn't make sense to occupy the whole
area.

Simply scaling down an available SVG of the tangram didn't work well.
The individual shapes were not recognizable because the spacing between
them was too thin. I tried removing the spacing and applying different
opacities for each shape, but that didn't yield enough contrast between
the shapes either.

The second approach was to just use the outlines. It sort of worked, but
looked a bit messy in the places when the outlines are denser than the
tangram shapes:

|  dark  | light  | 
|---|----|
| <img width="192" alt="Screenshot 2024-02-05 at 22 55 46"
src="https://github.com/zed-industries/zed/assets/43472/d0029f49-675d-40ac-96d8-788a29706bad">
| <img width="195" alt="Screenshot 2024-02-05 at 22 56 05"
src="https://github.com/zed-industries/zed/assets/43472/d2de922a-70ec-4bd1-9033-db9a5201e9bd">
|

I then tried to remove the main outline and use the maximum space for
the tangram. That let me increase the spacing between the shapes. I also
rounded them a little bit, to make them look similar to other icons from
Zed. The end result looks clean and the shapes are still recognisable.

Approaches I tried next to an existing icon from Zed:

This takes down LLVM IR size of theme_selector from 316k to ~250k. Note
that I do not care about theme_selector in particular, though it acts as
a benchmark for smaller crates to me ("how much static overhead in
compile time does gpui have").

The title is a bit dramatic, so just to shed some light: by leaking a
type I mean forcing downstream crates to codegen it's methods/know about
it's drop code. Since SubscriberSet is no longer used directly in the
generic (==inlineable) methods, users no longer have to codegen `insert`
and co.

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.

Release Notes:

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.

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.)

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

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.
