/**
 * Adapter registry for the Issues & PRs surface.
 *
 * Deliberately dumb: a map from provider id to adapter, filled at module load.
 * Adding GitLab is one file in `providers/` plus one line in `index.ts` — the
 * same shape as the internal-MCP `defineServer()` pattern and the integration
 * provider registry, so there is one thing to learn rather than three.
