Subject: [PATCH] Stabilize cross-platform tests and directory-change fork
 permissions (#59369)

## Why

Tests need to distinguish slow subprocess startup from operation timeouts and wait for asynchronous work before asserting results or cleaning up fixtures.

## What changed

- Synchronize subprocess readiness, queued-turn completion, and matching UI events; allow more time for cold startup and separate startup from shutdown deadlines.
- Adapt Windows fixtures and permission expectations, provide the voice-host test runtime DLL path, and normalize platform paths and animated status snapshots.
- Use current configuration permissions when changing directories in embedded TUI sessions, while retaining saved permissions for remote sessions.
- Allow the release prompt-prefix comparison to accept the exact image-tool description update that removes image detail options, and refresh the corresponding tool snapshot.

## Testing

Extend inherited-session metadata coverage to both legacy and paginated thread history, including persisted history mode and revision-aware resume.
