Registering multiple Mach port names with the bootstrap server at runtime is not how macOS expects it to be used — the bootstrap server is meant for static services, and the only reason we used it originally was so child processes could reach back to the UI process. Remove bootstrap_transport_over_socket(), which had both sides register dynamic names with the bootstrap server and exchange them over a socket. Instead, WebDriver and BrowserProcess connections now go through MachPortServer instances directly. When a non-child process contacts a MachPortServer, the server creates a port pair on demand (detected via sysctl ppid check) and returns the local half immediately. This keeps bootstrap server usage limited to the one original case: child processes looking up their parent's MachPortServer. WebDriver Session now runs its own MachPortServer per session. --webdriver-content-path becomes --webdriver-mach-server-name on macOS. Spare WebContent launches are skipped when a WebDriver session is active to avoid bootstrap races.
