A Bazzite/SteamOS Gaming↔Desktop switch tears the old compositor down and can
take 15s+ to bring the new one up — longer than the capture-loss rebuild's
~10s window, so the session failed mid-switch ("disconnect — session failed")
and forced the client to cold-reconnect. Retry the rebuild within a 40s budget
instead of giving up after one round, and re-detect the live compositor on
each attempt so the stream follows the box to whatever session comes up (a new
instance of the same compositor, or a different one — the kind-change case).
The QUIC keepalive runs on its own thread, so the client stays connected
(frozen on the last frame) and the stream resumes when the new output appears,
with no reconnect.
