The daemon re-validates the CDP connection before every browsing command via
is_connection_alive() (Browser.getVersion, 3s timeout). It treated any
timeout-or-error as "dead" and tore the connection down + reconnected.
For an externally-attached browser (the stealth fork's default — the user's
real Chrome), a timed-out probe is almost always Chrome being briefly busy or
showing the Chrome 136+ "Allow remote debugging?" consent modal, which blocks
CDP responses until the user clicks Allow. Tearing the already-consented
connection down forces a reconnect that re-pops the consent prompt — repeated
on every command this becomes an endless prompt loop, and the close +
multiple new /devtools/browser WS probes storm Chrome into a freeze.
Fix: distinguish the probe outcome.
- Responded -> alive
- TransportError -> dead (WS closed/reset; user closing Chrome lands here too,
so zombie-socket detection is preserved)
- TimedOut -> alive for an external attach (don't tear down a consented
connection on transient slowness); dead for a browser we
launched ourselves (a real hang worth reconnecting, and no
consent modal in play).
Extracted the verdict into a pure connection_alive_from_probe() with unit
tests covering all outcomes. No behavior change for locally-launched browsers.
