- Set `.SystemUIFont` as the GPUI default font.
- Add `Arial` to font fallback list.
- Add `Adwaita Sans` to default fallback list for Gnome.
- Move `Ubuntu` font to front of Gnome to make sure Ubuntu System takes
priority over `Ubuntu` font.
Our application get some crash report:

This change to add `Arial` to fallback list, this font was included in
macOS and Windows.

Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.
## Changes
- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.
## Benefits
- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.
Follows Rust guidelines; run `./script/clippy` for verification.
- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

This PR also introduces `Context::processor`, a sibling of
`Context::listener` that takes a strong pointer to entity and allows for
a return result.

As https://github.com/zed-industries/zed/discussions/24260 I mentioned
issue.
Make a complex data table example to test the text rendering
performance.
This example also can be an example to show how to build a large data
table.
```bash
cargo run -p gpui --example data_table
```

I will try to do some test.
For example: With a threshold for the hold number of caches in
`FrameCache`, and only when the threshold is greater than a certain
number, some caches are released, or when a certain time has passed. I
am not sure if this is feasible.
This example is added to help us to test.
