## Why
Approval and item IDs can collide across concurrent threads. Tracking pending app-server approvals by ID alone can therefore resolve, submit, or dismiss a request from the wrong thread.
## What changed
- Key command execution, file change, and permissions approvals by both thread ID and approval ID.
- Route approval responses through the originating thread and require the thread to match when processing resolution notifications or dismissing approval prompts.
- Canonicalize parseable thread IDs so equivalent UUID representations still match.
## Testing
- Cover colliding approval IDs across threads, mismatched resolution notifications, prompt dismissal, and response routing for primary and background threads.
