feat: initial release — traefik, unifi, ups plugins

First-party plugins for Fabled Scryer (https://github.com/bvandeusen/fabledscryer).

traefik: Prometheus metrics scraping, stats history, access log parsing (GeoIP optional)
unifi:   UniFi controller integration — WAN health, devices, clients, DPI, events
ups:     UPS monitoring via NUT (Network UPS Tools), Ansible shutdown automation

Each plugin follows the Fabled Scryer plugin contract:
  setup(app), get_scheduled_tasks(), get_blueprint()

index.yaml lists all three plugins in the catalog format. Populate
checksum_sha256 entries once release zips are published via GitHub Releases.
