New tool: tools/crisis_tool.py
- Wraps the-door's canonical crisis detection (detect.py)
- Scans user messages for despair/suicidal ideation
- Classifies into NONE/LOW/MEDIUM/HIGH/CRITICAL tiers
- Provides recommended actions per tier
- Gateway hook: scan_user_message() for pre-API-call detection
- System prompt injection: compassion_injection based on crisis level
- Optional escalation logging to crisis_escalations.jsonl
- Optional bridge API POST for HIGH+ (configurable via CRISIS_BRIDGE_URL)
- Configurable via crisis_detection: true/false in config.yaml
- Follows the-door design principles: never computes life value,
never suggests death, errs on side of higher risk
Also: tests/test_crisis_tool.py (9 tests, all passing)
