enliven

Make an Electron or web app measurably faster without losing a feature, and prove it. The agent builds a repeatable A/B harness that drives the real production build through Playwright and reads Chromium's own counters over the DevTools protocol, finds the cause of the cost with a Blink style-invalidation trace and a React commit probe instead of guessing, fixes root causes, re-measures the same way, and writes a self-contained HTML report that shows the regressions as loudly as the wins. Use when the user asks to profile, speed up, slim down, find memory leaks in, or benchmark before and after on a desktop or web app, or asks for a performance report.
