notes: >-
  Recent window only — the live release-notes page is the source of truth. Lightrun does
  not label releases breaking vs non-breaking, so `breaking` is recorded as unknown rather
  than guessed. The dominant theme across this window is the MCP surface: new asynchronous
  tool quartets, org-level MCP access control, and Public API endpoints catching up to what
  MCP already exposes.
