Subject: [PATCH] Skip build for lightweight stages (analyse, architect,
 release, maintenance)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

These stages only read code and post comments — no need for npm install,
frontend build, Playwright, or migrations. Saves several minutes.
