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

crisis/metrics.py:
  CrisisMetrics class — aggregate crisis detection metrics
  Privacy-first: stores only counts, never user content
  Daily JSONL files in ~/.the-door/metrics/
  get_summary(days) → AggregateMetrics
  get_report(days) → human-readable report
  get_json(days) → JSON export
  CLI: python3 -m crisis.metrics --summary/--json

crisis/__init__.py:
  Export CrisisMetrics, AggregateMetrics

Makefile:
  make metrics      → summary report
  make metrics-json → JSON export

tests/test_crisis_metrics.py: 6 tests
  record_session, summary, report, JSON export
