Crash self-report + round-completed latch + PDB archiving

Browse Source 
CRASH SELF-REPORT (the #35/#41 heisenbug hunt): every unhandled
exception now logs its code, address, and an EBP-walked stack as
module-relative offsets (btl4+0xNNNN) into BT_LOG before dying --
any field crash on any machine hands us a resolvable stack.  The
walker is per-dereference guarded (a corrupt chain truncates).
BT_CRASHTEST=1 exercises the path end-to-end (verified: forced AV
logs code/addr/5-frame stack).  mkdist archives each build's PDB
next to its zip so offsets resolve per distributed version.

Context: a flaky release-only crash in the mech build path surfaced
during #38 rigs -- it moves with build layout, spares neither peer,
and masks under a debugger heap (13 clean cdb runs vs 2/3 crashes
without).  A real latent memory bug; the self-report will catch it
wherever it strikes next.

ROUND-COMPLETED LATCH (issue #38, awaiting verification): relay-mode
clients refuse RunMission after a round has ended -- the lobby-loop
relaunch owns the next round (in-process round 2 rebuilt every
player/mech entity on stale globals; matchlog caught player=3:1->3:36
in one generation).  Latch sets ONLY when the stop ends a RUNNING
mission (a stray pre-mission StopMission must not poison round 1 --
the first cut ate a legit launch, caught + fixed in rig).  Regression
verification pending (contaminated by the heisenbug above).
