RentEarth API

The axum-rentearth service resolves RentEarth desktop downloads from itch.io (via the shared jedi itch client) and serves the Vite + TanStack web at /.

It mirrors axum-chuckrpg: /downloads/{platform} redirects to the signed itch URL, /downloads renders an askama page, and /api/downloads exposes the live per-platform build state the web consumes.
