feat: ship production deploy, Playwright e2e, and agent implementer

Add Docker atomic deploy tooling, CI, Playwright smoke/visual suite,
shared industrial theme, physics invariants, quality-mode wiring,
and a worktree-isolated agent implementer MVP with hard safety limits.

+## Notes
+
+- **Headless Chromium WebGL is not a GPU FPS measurement.** Values ~9 FPS / p95 ~200 ms reflect software/SwiftShader-like rendering in CI/headless, **not** desktop Chrome with NVIDIA. Do not claim 30–60 FPS from this pass.
+- For jury/demo FPS, measure in headed Chromium on the presentation machine (`npm run test:e2e:headed` + DevTools Performance) or Engineering Details FPS meter.
+- Draw calls / triangles require WebGL inspector in headed mode; not available in this headless pass.
+- Demo quality mode keeps `shadows=false` and `effectsEnabled=false` for stable real-device FPS (see `qualityMode.ts`). High mode may enable shadows.
+- Raw JSON: `agent/reports/perf-metrics.json`
+- Runtime error (if any): none
