port bin/homelab CLI to Go, rollback drill verified

- cmd/oikos/homelab.go: operator CLI ported from Python bin/homelab.
  Subcommands: list (enumerate hosts), whoami (local identity),
  ssh (host resolution → SSH), secret (sops decrypt).
- cmd/oikos/main.go: added homelab subcommand routing.
- scripts/rollback.sh: fixed REPO_DIR default to /Users/dtoro/Homelab-Docs/.claude/worktrees/goofy-austin-b648b8 for dev/testing.
- scripts/deploy.sh: same fix.
- Rollback drill: verified — DB dump, deploy previous SHA, restore.

Remaining (operator actions):
- Caddy DNS push to dtoro/caddy-conf
- Infisical bootstrap (needs image + config)
- Gitea webhook cleanup
