Updates from Gitea, step 1: the model (host-tested)

A streaming JSON scanner (a 33 KB list of releases costs a few hundred bytes), the release reader built on it, HTTP response heads and chunked bodies, URLs, and the decisions: which release is an update, whether to announce it, and which download URLs the device takes. Tested against the real answers of git.twis.la. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
