PROCESS_WITH_RENDERER_PORT_REGEX =

Matches a Procfile process line that both (a) sets RENDERER_PORT via env var AND (b) starts a recognized Node Renderer command. Hard-coded ports intentionally do not match — doctor always nudges users toward the RENDERER_PORT env-var idiom the generator writes (overridable, self-documenting). The recognized-command branch mirrors NODE_RENDERER_PROCESS_REGEX in pro_setup.rb so the doctor accepts the same set of invocations the generator does (pnpm/npm/yarn with optional ‘run`).
