feat: v2.1.0 — Systemd Timer + Performance Optimierungen

Neue Features:
- install-timer / remove-timer Befehle
- Tägliche automatische AUR-Scans via systemd
- Cache-Status-Anzeige mit Alter und TTL
- AUR-Score aus Paket-Info (Votes, Popularität, Maintainer)
- Performance: ~7x schneller durch gecachte AUR-Prüfung
- PKGBUILD-Analyse nur bei verbose oder IOC-Match

Verbesserungen:
- Keine False-Positives für offizielle Repo-Pakete
- HedgeDoc 1931 IOCs live geladen
- Journal-Logging für Timer-Scans
