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.
