FN-7239: scope executor prompts and quarantine stale pause test

Browse Source 
Scope missing executor prompts safely while keeping graph coverage aligned with the post-cutover workflow route.

- Treat absent executor prompts as empty before worktree path scoping.
- Update graph retry, parity, and smoke expectations for plan review, completion summary, and post-merge traversal.
- Quarantine only the stale executor-pause direct-dispatch suite with a ledger entry and engine-default exclude.
