Closes#24672
This PR complements a feature added earlier by @JosephTLyons (in
https://github.com/zed-industries/zed/pull/32353) where the text is
considered as the tab title in a new buffer. It piggybacks off that
change and sets the title as the suggested filename in the save dialog
(completely mirroring the same functionality in VSCode):

Release Notes:
- Text entered in a new untitled buffer is considered as the default
filename when saving
This PR makes it so we send the `User-Agent` header on the WebSocket
connection requests when connecting to Collab.
We use the user agent set on the parent HTTP client.

Instead of selecting a screen to share arbitrarily, we'll now allow user
to select the screen to share. Note that sharing multiple screens at the
time is still not supported (though prolly not too far-fetched).
Related to #4666

Release Notes:
- Added screen selector dropdown to screen share button

Closes #ISSUE
`cx.intercept_keystrokes` functions as a sibling API to
`cx.observe_keystrokes`. Under the hood the two API's are basically
identical, however, `cx.observe_keystrokes` runs _after_ all event
dispatch handling (including action dispatch) while
`cx.intercept_keystrokes` runs _before_. This allows for
`cx.stop_propagation()` calls within the `cx.intercept_keystrokes`
callback to prevent action dispatch.
The motivating example usage behind this API is also included in this
PR. It is used as part of a keystroke input component that needs to
intercept keystrokes before action dispatch to display them.

The major change in schemars 1.0 is that now schemas are represented as
plain json values instead of specialized datatypes. This allows for more
concise construction and manipulation.
This change also improves how settings schemas are generated. Each top
level settings type was being generated as a full root schema including
the definitions it references, and then these were merged. This meant
generating all shared definitions multiple times, and might have bugs in
cases where there are two types with the same names.
Now instead the schemar generator's `definitions` are built up as they
normally are and the `Settings` trait no longer has a special
`json_schema` method. To handle types that have schema that vary at
runtime (`FontFamilyName`, `ThemeName`, etc), values of
`ParameterizedJsonSchema` are collected by `inventory`, and the schema
definitions for these types are replaced.
To help check that this doesn't break anything, I tried to minimize the
overall [schema
diff](https://gist.github.com/mgsloan/1de549def20399d6f37943a3c1583ee7)
with some patches to make the order more consistent + schemas also
sorted with `jq -S .`. A skim of the diff shows that the diffs come
from:
* `enum: ["value"]` turning into `const: "value"`
* Differences in handling of newlines for "description"
* Schemas for generic types no longer including the parameter name, now
all disambiguation is with numeric suffixes
* Enums now using `oneOf` instead of `anyOf`.

This is an easy way to shave some microseconds off the critical path for
frame rendering. On my machine this reduces typical frame rendering
latency by ~100 microseconds, probably quite a bit more on slower
machines.
Here is how long it typically takes to drop elements from the arena,
from a fairly brief run:

Instead of a menagerie of macros for implementing `Action`, now there
are just two:
* `actions!(editor, [MoveLeft, MoveRight])`
* `#[derive(..., Action)]` with `#[action(namespace = editor)]`
In both contexts, `///` doc comments can be provided and will be used in
`JsonSchema`.
In both contexts, parameters can provided in `#[action(...)]`:
- `namespace = some_namespace` sets the namespace. In Zed this is
required.
- `name = "ActionName"` overrides the action's name. This must not
contain "::".
- `no_json` causes the `build` method to always error and
`action_json_schema` to return `None`
and allows actions not implement `serde::Serialize` and
`schemars::JsonSchema`.
- `no_register` skips registering the action. This is useful for
implementing the `Action` trait
while not supporting invocation by name or JSON deserialization.
- `deprecated_aliases = ["editor::SomeAction"]` specifies deprecated old
names for the action.
These action names should *not* correspond to any actions that are
registered. These old names
can then still be used to refer to invoke this action. In Zed, the
keymap JSON schema will
accept these old names and provide warnings.
- `deprecated = "Message about why this action is deprecation"`
specifies a deprecation message.
In Zed, the keymap JSON schema will cause this to be displayed as a
warning. This is a new feature.
Also makes the following changes since this seems like a good time to
make breaking changes:
* In `zed.rs` tests adds a test with an explicit list of namespaces. The
rationale for this is that there is otherwise no checking of `namespace
= ...` attributes.
* `Action::debug_name` renamed to `name_for_type`, since its only
difference with `name` was that it
* `Action::name` now returns `&'static str` instead of `&str` to match
the return of `name_for_type`. This makes the action trait more limited,
but the code was already assuming that `name_for_type` is the same as
`name`, and it requires `&'static`. So really this just makes the trait
harder to misuse.
* Various action reflection methods now use `&'static str` instead of
`SharedString`.

Currently, there’s no way to modify the cursor style of the active drag
state after dragging begins. However, there are scenarios where we might
want to change the cursor style, such as pressing a modifier key while
dragging. This PR introduces an API to update and read the current
active drag state cursor.

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!(...));`

When we use `window_handle` to draw WebView on Windows, this will crash
by:
This error caused by when used WebView2.
```
thread 'main' panicked at crates\gpui\src\app\async_context.rs:91:28:
already borrowed: BorrowMutError
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread 'main' panicked at library\core\src\panicking.rs:221:5:

```
Try this https://github.com/tauri-apps/wry/pull/1383 on Windows can
replay the crash.
In fact, we had done [a similar fix around August last
year](https://github.com/huacnlee/zed/pull/6), but we used the unsafe
method to avoid crashes in that version, we felt that it was not a good
change, so we do not make PR.
Today @sunli829 thought about it again and changed the method. Now using
`try_borrow_mut` is similar to the previous `borrow_mut`.

This fixes a deadlock that would occur when `DapStore` had its on quit
handler called. The deadlock was caused by `DapStore` spawning on the
main thread while `App::shutdown` blocks the main thread.
We added a debug_panic in GPUI that panics if a foreground task is
spawned while the App context is shutting down. This will help tests
catch hangs in `cx.on_app_quit` calls.

Before this change we used our own copy of `cx.key_context()` when
matching.
This led to races where the context queried could be either before (or
after) the
context used in dispatching.
To avoid the race, gpui now passes out the context stack actually used
instead.
Release Notes:
- Fixed a bug where the Key Context View could show the incorrect
context,
causing confusing results.
Closes#27414
`ImageCache` is independent of the original image loader and can
actively release its cached images to solve the problem of images loaded
from the network or files not being released.
It has two constructors:
- `ImageCache::new`: Manually manage the cache.
- `ImageCache::max_items`: Remove the least recently used items when the
cache reaches the specified number.
When creating an `img` element, you can specify the cache object with
`Img::cache`, and the image cache will be managed by `ImageCache`.
In the example `crates\gpui\examples\image-gallery.rs`, the
`ImageCache::clear` method is actively called when switching a set of
images, and the memory will no longer continuously increase.

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()`.

While working on implementing `add_recent_documents` for Windows, I
found that the process is significantly more complex compared to macOS.
On macOS, simply registering the `add_recent_documents` function is
enough, as the system handles everything automatically.
On Windows, however, there are two cases to consider:
- **Files opened by the app**: These appear in the "Recent" section (as
shown in the screenshot, "test.txt") and are managed automatically by
Windows (by setting windows registry), similar to macOS.

- **Folders opened by the app**: This is more complicated because
Windows does not handle it automatically, requiring the application to
track opened folders manually.
To address this, this PR introduces a `History Manager` along with
`HistoryManagerEvent::Update` and `HistoryManagerEvent::Delete` events
to simplify the process of managing recently opened folders.

This pull request does two things:
1. Adds a setting to force Zed to use the built-in prompts, instead of
the system provided ones. I've personally found the system prompts on
macOS often fail to respond to keyboard input, are slow to render
initially, and don't match Zed's style.
2. Makes the previously Linux-only Zed provided prompts available to
everybody using the above setting.
Release Notes:
- Added support for a built-in prompting system, regardless of platform.
Use the new `use_system_prompts` setting to control whether to use the
system provided prompts or Zed's built-in system. Note that on Linux,
this setting has no effect, as Linux doesn't have a system prompting
mechanism.
This is the core change:

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app

- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
