Implement the Gitea extension

The repository was a bare Nova scaffold. This builds it out to match the capabilities of the official Gitea VS Code extension. Sidebar sections: - Current Branch: pull requests and workflow runs for the checked-out branch, with a current/all/pinned branch filter - Workflows: runs grouped by workflow file, expanding into jobs, steps, and artifacts - Pull Requests: open pull requests across repositories, expanding into reviews, review comments, and changed files - Settings: per-instance connection state, plus repository Actions secrets and variables Commands cover run control (re-run, re-run failed jobs, re-run a job, cancel), job logs, artifact download/reveal/open, pull request overview, diff, checkout, creation, merge and close, the full review cycle, and secret and variable management. Multiple instances are supported, routed by git remote host, with tokens held per instance in the Keychain. Nova exposes no webview, diff editor, editor decorations, or extension status bar, so four features are shaped differently from the VS Code original: the pull request timeline renders as Markdown, diffs open as unified .diff documents, review comments are published through an IssueCollection so they appear in the gutter and the Issues sidebar, and a failed run posts a notification. OAuth and insecureSkipVerify have no Nova equivalent and are omitted. README.md records all of this. Endpoints were taken from Gitea's published swagger.v1.json. Servers predating the workflow runs API fall back to /actions/tasks. Tests/ runs the extension's real code under Node against a stubbed Nova runtime and a canned Gitea instance: 88 checks, no install step and no network. Images are generated by Tools/make-icons.py.
