feat(agent-teams): implement teammate control tools (force_kill, process_shutdown_approved)

- Add force_kill_teammate tool for immediate teammate removal
- Add process_shutdown_approved tool for graceful shutdown processing
- Both tools validate team-lead protection and teammate status
- Comprehensive test coverage with 8 test cases
- Task 10/25 complete
