Crashing on macOS due to `spawn Xvfb`

[jamiew]

I noticed in the changelog that Linux support was added via Xvfb. On my late-model Apple Silicon mac, I can no longer run the server via npx:

npx -y @automatalabs/mcp-server-playwright

=>

Error: spawn Xvfb ENOENT

Thank you guys for the bug report, much appreciated. I just reverted the offending commits and will be publishing the updated npm package right after.
