fix: install Chromium dependencies for Puppeteer in CI

GitHub Actions Ubuntu runners don't have all required system libraries
for headless Chrome. Added apt-get install step for Puppeteer dependencies.

Installed packages:
- libnss3, libatk*, libcups2, libdrm2 — core browser libs
- libxkbcommon0, libxcomposite1, libxdamage1, libxfixes3, libxrandr2 — X11
- libgbm1 — GPU/graphics
- libasound2 — audio (headless doesn't need it, but Chromium checks)

This runs before npm ci to ensure Puppeteer can download and run Chrome.
