Serveur Go : recherche GitHub par critères

- /api/search traduit les filtres en requête GitHub (langage, étoiles,
  activité, création, licence, topic, forks, archivés, good first issues)
- cache mémoire des recherches identiques (CACHE_TTL) et suivi du quota
- /api/status, /healthz, authentification basique optionnelle
- Dockerfile et docker-compose.yml
