feat(docker): add optional Chromium + Xvfb install in Docker image

Browse Source 
Adds a build arg OPENCLAW_INSTALL_BROWSER that, when set, pre-installs
Chromium (via Playwright) and Xvfb into the Docker image. This eliminates
the 60-90 second Playwright install that otherwise happens on every
container start when browser features are used.

Usage:
  docker build --build-arg OPENCLAW_INSTALL_BROWSER=1 -t openclaw:browser .

Without the build arg, behavior is unchanged (no Chromium in image).
