`extension connect` rewrote argv to ["connect", <relay-url>] but the connect path
reads flags.cdp — parsed earlier from the original argv ("extension connect" →
None). So the relay URL was dropped and the daemon ran AUTO-CONNECT, grabbing
whatever Chrome it could discover: a stale remote-debugging Chrome on :9222
(indefinite hang), or triggering Chrome's "Allow remote debugging?" prompt on
machines without one. This is the EAGAIN/hang hermes hit on --session connect.
Fix: set flags.cdp = Some(relay_url) (+ disable auto_connect) in the
extension-connect branch so the daemon connects to the live relay endpoint.
Diagnosed via local repro (trace showed connect_cdp resolving ws://...:9222/
devtools/browser/... instead of the relay's ws://...:<port>/<guid>).
