gitea: full nox module — client, tools and events (ADR 0044/0046)

Git hosting. 15 tools (repos, issues, PRs, labels, api passthrough) moved out
of the shared sdk. Emits repo.created (from a light poll, catching repos born
of git push or the web UI), issue.opened and pull.merged (from the tools at the
moment of the action) — the poll owns repo.created alone so it is never
announced twice. Typechecks; manifest parses.
