Lobby loop: auto-rejoin between rounds + seat reclaim + live mission edits

Browse Source 
The between-rounds arcade flow (first-playtest-night field request): at
mission end every pod exited, seats dropped, and every round required
everyone to re-run join.bat with no way to adjust the mission.

1. AUTO-REJOIN: StopMission (operator END / mission clock -- NOT a
   window close) sets gBTMissionStoppedByConsole; after the matchlog
   upload btl4main relaunches the pod into the join wait with the same
   cmdline (BT_CALLSIGN/BT_MECH ride the inherited environment).

2. SEAT RECLAIM: the assigned tag is mirrored file-scope
   (BTRelaySelfTag) and re-presented as the 3rd SEAT_REQUEST payload
   field (BT_SEAT_CLAIM); the relay holds a dropped seat for its tag
   for 90s and a returning player gets their EXACT seat back -- static
   ordering across rounds, the real-pod model.  Non-claim joiners skip
   reclaim-held seats.

3. LIVE MISSION EDITS: the console gains "Apply mission settings"
   (enabled while a session runs) writing arena/time/weather/length
   into the session egg; the relay re-reads the file at round reset and
   egg release (roster shape locked mid-session).

Verified 2-pod 3-round: pods self-relaunched after each clock end; the
SECOND-to-rejoin still reclaimed its original seat (ordering held); the
between-rounds edit landed ("mission length now 75s").  Known edge
noted in the KB: a stale ready flag from a not-yet-exited old conn can
satisfy the launch gate mid-rejoin -- operators launch on green dots.
