Fix a segfault in CVDisplayLink
We see 1-2 crashes a day on macOS on the `CVDisplayLink` thread.
```
Segmentation fault: 11 on thread 9325960 (CVDisplayLink)

With the help of the Zed AI, I dove into the crash report, which looks
like this:

Using lldb to disassemble `CVHWTime::reset()` (and the AI to interpret
it), the crash is caused by dereferencing the pointer at the start of
the CVHWTime struct + 0x1c8. In this case the pointer has (the clearly
nonsense) value 0x2e (and 0x2e + 0x1c8 = 0x1f6, the failing address).
As to how this could happen...
Looking at the implementation of `CVDisplayLinkRelease`, it calls
straight into `CFRelease` on the main thread; and so it is not safe to
call `CVDisplayLinkRelease` concurrently with other threads that access
the CVDisplayLink. While we already stopped the display link, it turns
out that `CVDisplayLinkStop` just sets a flag on the struct to instruct
the io-thread to exit "soon", and returns immediately. That means we
don't know when the other thread will actually exit, and so we can't
safely call `CVDisplayLinkRelease`.
So, for now, we just leak these objects. They should be created
relatively infrequently (when the app is foregrounded/backgrounded), so
I don't think this is a huge problem.
Release Notes:
- Fix a rare crash on macOS when putting the app in the background.
Closes#16527
Release Notes:
- Added MacOS titlebar double-click action

Unfortunately, Apple doesn't seem to make the "Fill" API public or

The before version GPUI used `Cancel` for cancel text, if we use
non-English text (e.g.: "取消" in Chinese), then the press `Esc` to cancel
will not work.
So this PR to change it by use `PromptButton` to instead the `&str`,
then we can use `PromptButton::cancel("取消")` for the `Cancel` button.
Run `cargo run -p gpui --example window` to test.

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This glyphs field is usually larger than 8 elements, and SmallVec is not
efficient when it cannot store the value inline.

This PR adds a new `PlatformKeyboardLayout` trait with two methods:
`id(&self) -> &str` and `name(&self) -> &str`. The `id()` method returns
a unique identifier for the keyboard layout, while `name()` provides a
human-readable name. This distinction is especially important on
Windows, where the `id` and `name` can be quite different. For example,
the French layout has an `id` of `0000040C`, which is not
human-readable, whereas the `name` would simply be `French`. Currently,
the existing `keyboard_layout()` method returns what's essentially the
same as `id()` in this new design.
This PR implements the `name()` method for both Windows and macOS. On
Linux, for now, `name()` still returns the same value as `id()`.

Seems to be very similar to
https://github.com/zed-industries/zed/pull/28059
Edit: Updated the reproduction-steps as I missed something.
The method without a check currently causes my debug-builds to crash on
the regular if I:
- Run a debug build and open it fullscreen in a dedicated space on my
Mac.
- Work on any of the built-in languages (e.g. remove some content from
any `highlights.scm`)
- Reopen the workspace with the debug-build.
- Crash.
~~We might actually be able to revert the changes made in
https://github.com/zed-industries/zed/pull/21510 and just add the
null-check. Then again, I am not at all sure whether that would work.~~
See comment below.

Use the `NSOperatingSystemVersion` struct provided by the cocoa crate
instead of our own. Additionally we can directly use
`isOperatingSystemAtLeastVersion` instead of manually implementing
version comparison logic.
The `isOperatingSystemAtLeastVersion` instance method has been available
since MacOS 10.10, which released a decade ago.
Documentation for `isOperatingSystemAtLeastVersion `:

While building my own application using GPUI, I found that the `key_up`
event doesn't fire on Windows or macOS, with each platform failing for
different reasons. These events aren't used anywhere in Zed yet, so it
makes sense that the issue hasn't already been caught.
I don't have a Linux machine set up right now, so I don't know if these
events fire correctly on Linux or not.
---
Without this fix, a simple layout like the following:
```rust
div()
.on_key_down(cx.listener(|_, event, _, _| println!("Key down: {:?}", event)))
.on_key_up(cx.listener(|_, event, _, _| println!("Key up: {:?}", event)));
```
...would result in the following logs if the 'a' key was pressed:
```text
Key down: KeyDownEvent { keystroke: Keystroke { modifiers: Modifiers { control: false, alt: false, shift: false, platform: false, function: false }, key: "a", key_char: Some("a") }, is_held: false }
<eof>
```
With this fix, the `key_up` event fires correctly, resulting in the
following logs:
```text
Key down: KeyDownEvent { keystroke: Keystroke { modifiers: Modifiers { control: false, alt: false, shift: false, platform: false, function: false }, key: "a", key_char: Some("a") }, is_held: false }
Key up: KeyUpEvent { keystroke: Keystroke { modifiers: Modifiers { control: false, alt: false, shift: false, platform: false, function: false }, key: "a", key_char: None } }
<eof>
```
---
I've made the assumption that the `key_char` field shouldn't be set on
the `key_up` event since, unlike the `key_down` event, it's not an event
that may produce a character.
Happy to make any changes to this PR as required. If it would be
preferable to test this on Linux as well before it's merged, let me know
and I'll sort something out.
Hopefully this makes the experience of building new applications on GPUI
smoother, and potentially saves the Zed team some time if this event is
ever used in the future.

Closes#4461
Take 2 on https://github.com/zed-industries/zed/pull/25040.
Fixes panic caused due to using `setHiddenUntilMouseMoves` return type
to `set` cursor on macOS.
Release Notes:
- Now cursor hides when the user is typing in editor. It will stay
hidden until it is moved again. This behavior is `true` by default, and
can be configured with `hide_mouse_while_typing` in settings.

Take 2 on https://github.com/zed-industries/zed/pull/26600. Now, it
doesn't break remote development.
Instead of using it in `build_classes`, it's now used in the `open`
method while creating a window. I found similar usage in other places
over internet.
Release Notes:
- Fixed issue where Zed would show mac native tabs when opening new
fullscreen windows on macOS.
Closes#26534
Recently, we fixed a title bar transparency issue that only occurred on
macOS 15.3 and later. PR:
https://github.com/zed-industries/zed/pull/26403
However, this seems to have broken multi-window fullscreen behavior on
earlier macOS versions. This PR adds versioning so that the title bar
transparency fix only applies to macOS 15.3.0 and later.
No release notes, as this bug only exists on main right now.

Currently, macOS doesn't support showing multi-keystroke shortcuts in
menu items. We can use an attributed string to differentiate them, but
that breaks consistency with traditional shortcuts.
This PR removes the hack of concatenating the multi-keystroke shortcut
to the title, as it looked a bit janky.

Closes#23735
This PR fixes an issue where Zed shows a transparent title bar in
fullscreen mode on macOS instead of the default gray one.
When switching to fullscreen mode, we change the title bar appearance to
opaque. When exiting fullscreen mode, we check the existing
`appears_transparent` flag that we pass to gpui to decide whether to
change the title bar back to transparent or not.
Note: Regardless of the `appears_transparent` flag, gpui should always
show an opaque title bar in fullscreen mode to prevent a broken
appearance, as macOS always displays the title bar in fullscreen mode
upon mouse interaction.

Release Notes:
- Fixed issue where Zed showed transparent titlebar in fullscreen mode
on macOS.
This reverts commit a8610fbd13.
I've been seeing some reports of segmentation faults that appear to
point to this change as the culprit.
Closes#25366.

- Community: Reverted #25040, so remove the corresponding entry from the
release notes.

This PR improves the coding experience by hiding the mouse while the
user is typing so it does not accidentally get in their way, making it
challenging to ready characters in the editor.
Release Notes:
- The following PR hides the cursor when the user is typing by adding a
new cursor style called `None`.
- Assuming the user does not move the mouse, it will stay hidden until
it is moved again.

Closes#24931
We've flipped back and forth at least once on whether the last or first
added keybinding should be shown in different contexts (See
[this](https://github.com/zed-industries/zed/issues/23621#issuecomment-2614061385)
as well as #23621 and the subsequent #23660)
This PR attempts to pick a side to stick with so that we are at least
consistent until #23660 is resolved and we have a way to determine which
keybinds to display in a manner that is both consistent and not
confusing

Closes#14170
To fix this, Zed needs to handle swipe events on its NSView. Logitech
mice don't send the usual Mouse4 and Mouse5 buttons but emulate swipe
gestures according to these websites:
- https://superuser.com/a/1216049
- https://sensible-side-buttons.archagon.net/
Of course, the user can map these buttons to something else in the
device's driver. Most IDEs (VSCode, IntelliJ) handle that correctly by
default so it would be good to follow that pattern.
Since it's my first contribution here, please let me know if I need to
enhance this PR to make it good enough for the main branch.
Release Notes:
- Fixed mouse navigation buttons on some devices (Logitech, Mac OS)

Ask @kvark to review.
I am not sure if there is anything I missed. I modified it according to
the
[particle](https://github.com/kvark/blade/tree/main/examples/particle)
example of Blade project. But the difference is that after the first
MSAA render, I did not do it a second time, I tested it and found it was
not necessary.
