Tamir Duberstein a95391160a Drive TUI stream animation from the foreground loop (#40644)
## Why

Stream animation ticks generated on a background thread can accumulate while the
TUI is busy, causing stale ticks to run after the animation stops or the chat
widget is replaced.

## What changed

- Replace the animation thread and `CommitTick` app event with a Tokio interval
  owned by the foreground event loop.
- Delay missed ticks instead of replaying a burst, and let pending app events run
  before animation work.
- Drop the interval when animation stops or the chat widget is replaced, while
  preserving `CommitTick` session-log entries.

## Testing

Add a paused-time test covering stable pacing, missed ticks, restart behavior,
and chat-widget replacement.
