### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).
Release Notes:
- Fixed a bug that was causing popovers to flicker.

This PR moves the Clippy configuration up to the workspace level.
We're using the [`lints`
table](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-lints-table)
to configure the Clippy ruleset in the workspace's `Cargo.toml`.
Each crate in the workspace now has the following in their own
`Cargo.toml` to inherit the lints from the workspace:
```toml
[lints]
workspace = true
```
This allows for configuring rust-analyzer to show Clippy lints in the
editor by using the following configuration in your Zed `settings.json`:
```json
{
"lsp": {
"rust-analyzer": {
"initialization_options": {
"check": {
"command": "clippy"
}
}
}
}
```
Release Notes:
- N/A
This PR sets up a `cargo xtask clippy` command for running `cargo
clippy` with our defined set of options.
The intent is to make this easier to manage as we start enabling more
Clippy rules.

This practice makes it difficult to locate todo!s in my code when I'm
working. Let's take out the bang if we want to keep doing this.

This is a follow up to #7945. The current behaviour reads the locale and
infers from that which type of time format should be used (12 hour/24
hour).
However, in macOS you can override this behaviour, e.g. you can use
en_US locale but still use the 24 hour clock format (Can be customized
under Settings > General > Date & Format > 24-hour time). You can even
customize the date format.
This PR uses the macOS specific `CFDateFormatter` API, which outputs
time format strings, that respect those settings.
Partially fixes#7956 (as its not implemented for linux)
Release Notes:
- Added localization support for all macOS specific date and time
configurations in chat
Before the change to `script/clippy`, bash ignored first `clippy`
invocation failure and CI moved on with Linux errors and warnings
emitted.
Release Notes:
- N/A

- [x] Fill in GPL license text.
- [x] live_kit_client depends on live_kit_server as non-dev dependency,
even though it seems to only be used for tests. Is that an issue?

Zed now is able to behave as if it's being started from CLI
(`ZED_FORCE_CLI_MODE` env var)
Zed CLI accepts regular binary file path into `-b` parameter (only *.app before),
and tries to start it as Zed editor with `ZED_FORCE_CLI_MODE` env var
and other params needed.
We temporarily let it grow when the message size exceed the limit,
but restore the buffer's capacity shortly after. This ensures that,
for each connection in its entire lifetime, we only ever use 1MB.
We still aren't handling CLI requests in the app, but this lays the foundation for bi-directional communication.
