"""Migration 2026-05-09c: source_health_checks und source_suggestions Schema.

Diese DDL stand bislang inline in routers/sources.py (in /health/run, /health/run-stream,
/health/search-fix). Phase 1 zieht sie hier raus, damit die Endpoints kein DDL mehr ausführen.

Ausführung:
    DB_PATH=/home/claude-dev/osint-data/osint.db python3 migrations/2026-05-09c_source_health_schema.py
    DB_PATH=/home/claude-dev/AegisSight-Monitor-staging/data/osint.db python3 migrations/2026-05-09c_source_health_schema.py
