Phase 1 Backend-Hygiene Quellen

- src/shared/ neu: source_rules, services/source_health, services/source_suggester,
  agents/claude_client als lokale Kopien aus dem Monitor-Repo (statt sys.path-Hack
  auf /home/claude-dev/AegisSight-Monitor/src - 5 sys.path.insert-Aufrufe entfernt)
- src/routers/sources.py: Imports auf shared. umgestellt, Header neu sortiert
  (Docstring zuerst, sys/os raus), Mojibake (Triple-Encoded UTF-8) via ftfy gefixt
- src/shared/services/source_suggester.py: Mojibake (Double-Encoded UTF-8) via ftfy gefixt
- migrations/2026-05-09c_source_health_schema.py NEU: source_health_checks +
  source_suggestions Tabellen mit Indizes (idempotent), gezogen aus 3 Inline-DDL-Blöcken
  in routers/sources.py (/health/run, /health/run-stream, /health/search-fix)
- src/config.py: CLAUDE_MODEL_MEDIUM und CLAUDE_MODEL_STANDARD ergänzt
  (vorher nur CLAUDE_MODEL_FAST - claude_client.py braucht alle drei)
- requirements.txt: httpx + feedparser explizit (im venv schon vorhanden, jetzt dokumentiert)

+"""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.
