claude-in-chrome MCP server now adopts into existing connection owner

The claude-in-chrome MCP server now wires its browser MCP server config into the session's existing MCP connections owner, logging a warning (no MCP connections owner on this session; the browser tools land on the next reconcile) if none exists yet and deferring adoption until the next reconcile. A related helper now detects MCP server configs referencing the --claude-in-chrome-mcp flag (via command or args), likely to identify the Chrome MCP connector during config processing.
