Remove entrypoint script, use direct node entrypoint

Removed the custom entrypoint script since the MCP registry doesn't
support conditional command-line argument passing. The server will
auto-launch Chrome with default settings (headless, 1280x720).

Users who need custom Chrome configurations can build and run the
server outside the registry using the standard npx approach with
command-line flags.
