Mirrors the slash command added in torrentclaw-web/.claude/commands.
With the global ~/.gitignore excluding .claude/ by default, the
gitignore override is required for project-shared commands/agents/hooks
to be checked in (settings.local.json and projects/ stay local).
/publish documents the full unarr release flow (bump + tag + binaries +
Hetzner + Docker Hub + smoke) as a single command, while GitHub Actions
remains unavailable for the torrentclaw org.
