## Message

```
gpui: Add system wake callback (#59831)

# Objective

GPUI apps currently don't have a cross-platform way to react when the
system wakes from sleep.

## Solution

Add `Application::on_system_wake`, backed by platform hooks for macOS,
Windows, and Linux. The platform listeners are registered lazily once an
app installs a wake callback.

## Testing
