initial: fdroidserver-ipfs image

Downstream of registry.gitlab.com/fdroid/docker-executable-fdroidserver:master, patched for publishing F-Droid repos over IPFS: - install Debian ipfs-cid so fdroidserver populates ipfsCIDv1 on every package file (APKs, icons, screenshots), which fdroidclient with an IPFS-gateway mirror routes via CID natively - rehash.py wrapper that adds ipfsCIDv1 to entry["index"], renames the index to a content-addressed filename, and re-signs entry.jar after `fdroid update` — closes the cache-busting gap on the index file itself - entrypoint.sh chains rehash automatically after any `fdroid update`, so existing fdroid-via-docker wrappers need no changes See SPEC.md for the rationale and Change 2's algorithm; README.md for end-user usage.
