Add structured progress comment format for agents:
- Standard format with Status, Phase, Tool Calls budget
- Completed/In-Progress/Blockers/Next sections
- Clear examples for starting, blocked, and failed states
- Guidance on when to post (every 20-30 tool calls)
Update sprint-status.md:
- Document how to parse progress comments
- Show enhanced in-progress display with tool call tracking
- Add progress comment detection to blocker analysis
This enables users to see:
- Real-time agent progress
- Tool call budget consumption
- Current phase and step
- Blockers as they occur
