feat: CLI command to view crisis metrics summary (closes #136)

Crisis Metrics CLI entry point:

  python3 -m crisis.metrics --summary    # weekly report
  python3 -m crisis.metrics --json        # JSON export
  python3 -m crisis.metrics --last 24h    # last 24 hours

Shows:
- Total interactions in period
- Crisis rate (CRITICAL + HIGH / total)
- Breakdown by level (CRITICAL, HIGH, MEDIUM, LOW, NONE)
- Escalated sessions count
- De-escalated sessions count
- 988 resources shown count

Loads metrics from ~/.the-door/metrics/*.json
