auto-connect resolved the DevToolsActivePort URL by first opening a
verification WebSocket (verify_ws_endpoint: connect, Browser.getVersion,
close) and only then opening the real connection. On Chrome 136+ the
"Allow remote debugging?" consent is granted per-connection, so the user's
single Allow click was consumed by the throwaway probe and the real
connection (opened afterwards) asked again — surfacing as repeated prompts
or a hung command after the user had already clicked Allow.
resolve_cdp_from_active_port now gates the direct DevToolsActivePort URL on
a consent-free TCP liveness check (tcp_port_alive) instead of a WebSocket
probe, so the real connection is the single WebSocket the user consents to.
A bare TCP connect does not trigger the consent flow (that fires on the CDP
upgrade), and the real connect_async has no client-side timeout, so it waits
for the user to click Allow at their own pace. verify_ws_endpoint removed;
discovery-order tests updated, plus a guard test that resolution opens no
WebSocket.
Verified live: single prompt on a real Chrome attach, then open + eval +
scroll x2 + eval with zero re-prompts and no freeze.
