tests/browser/server.py accepts --port 0: it binds 127.0.0.1:0 before building the app, holds that socket for its whole life and prints PM_TEST_SERVER_PORT=<n> to stdout. startBrowserServer defaults to port 0 and reads the announced port, so no port is reserved and released before the server binds and two launchers can no longer race for one. The "address already in use" retry and free-port.mjs are gone; --port N still works and is checked against the announcement.
