Subject: Enter git-forge-cloudflare

Runs git-forge on Cloudflare Containers with R2 for durable storage. A
Worker routes every request to one container through a Durable Object.
Inside it, syncd mirrors the data directory to the bucket and restores
it at boot, holding a write until it is durable.

git-forge is neither modified nor vendored: the image builds it from
its own repository at the commit named in forge.rev.
