/**
 * @file Detects whether this install is behind the newest published RELEASE of
 * its own repository, and can fast-forward onto that release tag on request.
 *
 * The release is read straight from the forge's REST API, derived from the
 * `origin` remote URL (`/api/v1/repos/<owner>/<repo>/releases/latest` — the
 * Gitea/Forgejo shape this project is hosted on), so the check needs no
 * hardcoded host and no credentials for a public repo. When no release can be
 * read — a non-HTTP remote, an offline machine, a repo with no releases yet —
 * detection degrades to the original commit-count comparison against the
 * canonical default branch rather than reporting a false "up to date".
 *
 * Two states the release model makes visible that a commit count cannot:
 * a checkout sitting AHEAD of the newest release tag is a `dev_build`, not an
 * up-to-date install; and an install living under `~/.claude/plugins/cache/`
 * is `plugin_managed`, where this process must NOT self-update — Claude Code
 * only re-resolves `${CLAUDE_PLUGIN_ROOT}` on `/reload-plugins`, a REPL-only
 * action no server can trigger, so a self-pull would leave a cache directory
 * whose name (a commit sha) no longer matches its contents.
