Add annotate_ack tool for attaching notes to acknowledgments
- Create dummy tool that allows agent to add custom notes to stream.thought.ack records
- Update acknowledge_post to accept optional note parameter
- Modify bot loop to capture notes from annotate_ack tool calls
- Add note field to stream.thought.ack records (null if not provided)
