xarmian 3cc3ba5e01 fix(web): flush the collaborative teardown on the events a suspended tab actually delivers (BUG-3030) (#1363)
* fix(web): flush the collaborative teardown on the events a suspended tab delivers (BUG-3030)

* fix(web): re-arm the teardown latch when a cancelled beforeunload leaves the page alive

codex round 2. 'Stay' cancels the navigation without firing pageshow or
visibilitychange, so the latch stayed set for the life of the page and every
later teardown flushed nothing — a worse loss than the one being fixed.

* test(web): make the teardown source guard enumerate handlers and fail closed

codex round 4. It rejected two literal spellings and checked runTeardownFlush()
appeared somewhere in the block, so a new handler writing through any other
call passed; and its function-body slicer failed OPEN when indexOf returned -1,
scanning most of a 7,900-line file.

* test(web): measure that one committed teardown writes exactly once (BUG-3030)

Lead withheld GO on this measurement rather than a reading: beforeunload ->
[setTimeout 0] -> pagehide, and if the timer wins the same bytes go out twice.
Measured 1 and 1, with no-edit controls at 0. Adds the jsdom leg for a hidden
tab nobody edited writing nothing.
