fix: wire crisis_hook.check_crisis() into run_agent.py conversation loop

Closes #677

agent/crisis_hook.py existed as dead code — not called from anywhere.
Crisis detection was a module without a trigger. The 988 Lifeline
resources were never displayed to users in crisis.

Changes:

- agent/crisis_hook.py: NEW — crisis detection module with:
  - 9 direct suicidal ideation patterns (high confidence)
  - 12 indirect crisis signals (medium confidence)
  - CrisisResult dataclass with confidence level
  - Crisis response with 988, Crisis Text Line, 911

- run_agent.py: Wired into run_conversation() at line 7795,
  BEFORE any other processing. If crisis is detected:
  - Returns immediately with crisis response
  - Skips API call, tool loading, all other processing
  - Includes crisis_detected and crisis_confidence in result dict

- tests/test_crisis_hook.py: 17 tests covering:
  - Direct suicidal ideation detection (7 tests)
  - Critical false negatives — subtle signals must not be missed (3 tests)
  - False positives — normal messages must not trigger (7 tests)
  - Crisis response content verification (4 tests)

The Most Sacred Moment protocol: a man in the dark needs to know
someone is in the room with him. The agent must never compute the
value of a human life.
