Initial commit — SvelteKit fleet manager for T5 Plutonium servers

Ports push_scripts.sh (1497 lines of bash) to a SvelteKit + SQLite web app
that manages a fleet of T5 Plutonium servers running on Komodo. Same push
and beta workflow as the shell script, with a live SSE pipeline view, a
!rt-token-gated auth modal that hard-pauses deployments on stale tokens,
per-file audit diffs, and a Komodo-container deployment target.

- Push/beta engines port the exact filter, held-by-beta, conflict, and
  stale-backup rules from the shell script
- SQLite (better-sqlite3) replaces script_metadata.json; a one-shot
  importer moves legacy state over on first boot
- 16 vitest tests cover push add/update/skip, beta open→rollback,
  open→promote, conflict guards, sweep frozen/manual branches, and IW4M
  login/status parsing
- docker/ + komodo/stack.toml deploy as a managed container on the same
  host as the game servers, /root/zombies bind-mounted at the same path
  the shell script used
