Josh McKinney 96a65ff0ed perf(tui): cap redraw scheduling to 60fps (#8499)
Clamp frame draw notifications in the `FrameRequester` scheduler so we
don't redraw more frequently than a user can perceive.

This applies to both `codex-tui` and `codex-tui2`, and keeps the
draw/dispatch loops simple by centralizing the rate limiting in a small
helper module.

- Add `FrameRateLimiter` (pure, unit-tested) to clamp draw deadlines
- Apply the limiter in the scheduler before emitting `TuiEvent::Draw`
- Use immediate redraw requests for scroll paths (scheduler now
coalesces + clamps)
- Add scheduler tests covering immediate/delayed interactions
