feat: Build crisis_synthesizer.py — learn from interactions (#36)

Logs anonymized crisis events, analyzes patterns, suggests improvements.
No user content stored. No identifying information.

Features:
- log_crisis_event(): anonymized event logging (level, indicators, profile, continued)
- analyze_patterns(): false positive rate, continuation rate, top indicators
- generate_suggestions(): keyword weight adjustment recommendations
- weekly_report(): JSON-structured weekly summary

Privacy: No user content, no IP, no session ID, no cross-conversation tracking.
