fix(docker): Address remaining PR #745 review comments

- Move Playwright install after node_modules copy to use pinned version
- Use local playwright binary instead of npx to avoid registry fetch
- Add --user automaker -w /app flags to docker exec commands
- Change bold text to proper heading in README (MD036 lint fix)

 The Docker image supports both AMD64 and ARM64 architectures. The GitHub CLI and Claude CLI are automatically downloaded for the correct architecture during build.
 
+##### Playwright for Automated Testing
+
+The Docker image includes **Playwright Chromium pre-installed** for AI agent verification tests. When agents implement features in automated testing mode, they use Playwright to verify the implementation works correctly.
+
+**No additional setup required** - Playwright verification works out of the box.
+
+#### Optional: Persist browsers for manual updates
+
+By default, Playwright Chromium is pre-installed in the Docker image. If you need to manually update browsers or want to persist browser installations across container restarts (not image rebuilds), you can mount a volume.
+
+**Important:** When you first add this volume mount to an existing setup, the empty volume will override the pre-installed browsers. You must re-install them:
+
+```bash
+# After adding the volume mount for the first time
+docker exec --user automaker -w /app automaker-server npx playwright install chromium
+```
+
+Add this to your `docker-compose.override.yml`:
+
+```yaml
+services:
+  server:
+    volumes:
+      - playwright-cache:/home/automaker/.cache/ms-playwright
+
+volumes:
+  playwright-cache:
+    name: automaker-playwright-cache
+```
+
+**Updating browsers manually:**
+
+```bash
+docker exec --user automaker -w /app automaker-server npx playwright install chromium
+```
