Removes the complex state machine and 10-second throttle (MIN_INJECTION_INTERVAL_MS)
that was causing background task completion to hang. The hook now:
- Uses straightforward error cooldown logic instead of complex injection throttling
- Removes unnecessary state tracking that was delaying continuation injection
- Maintains all safety checks (recovery mode, running tasks, error state)
- Keeps countdown behavior with toast notifications
Fixes#312 - Resolves v2.7.0 issue where background task completion would freeze
the agent due to injection delays.
