feat: Add maximum iterations limit for autonomous loop mode

Adds configurable iteration limits to prevent runaway autonomous loops
and provide predictable behavior, inspired by Ralph's design patterns.

Changes:
- Add AutonomousLoopConfig to daemon config with:
  - default_max_iterations: 10 (default for new tasks)
  - hard_limit: 50 (absolute maximum that cannot be exceeded)
  - no_change_threshold: 3 (consecutive runs without progress)
  - same_error_threshold: 5 (consecutive runs with same error)

- Add max_iterations and iteration_count fields to Task model
- Add iteration_limit_reached status to TaskStatus enum
- Pass max_iterations through DaemonCommand::SpawnTask
- Apply limits in CircuitBreaker during autonomous loop execution

When a task hits the iteration limit:
- Task status is set to "iteration_limit_reached" (not "failed")
- Clear message is logged about hitting the limit
- Task can be resumed with a higher limit if needed
