Replace socket daemon with direct CDP WebSocket connection

Drops the Unix socket subprocess in favor of talking CDP directly over
WebSocket from the extension. Removes the protocol's send/health helpers,
simplifies setup to just verifying Chrome's remote debugging port, and
tightens types in dynamic-tools. Bumps Node engine to >=22 and adds the
ws dependency.
