fix: de-duplicate crisis detector — single source of truth

Fixes #39

Problem: Two separate crisis detection systems existed:
- crisis_detector.py (legacy, root) — used by crisis_responder.py
- crisis/detect.py (module, newer) — used by crisis/gateway.py

Different keywords, different tiers, false positive fixes only in
the legacy file. Maintenance hazard.
Fix: crisis_detector.py is now a thin compatibility layer that
re-exports from crisis/detect.py (the canonical detector).
Legacy interface preserved: CrisisDetector, CrisisResult, detect_crisis.
All 84 tests pass. No behavioral regression.
