Respawn-reset audit: valve restore + peer smoke cleanup (both binary-grounded)

Operator reports audited vs the binary (full matrix in RESPAWN_REARM_PLAN
addendum):
- VALVES (real gap): Condenser reset @004ae534 was missing from the decomp
  export -- raw disasm shows it chains HEATSINK (coolant refill runs; the
  old body chained HeatableSubsystem per the stale TCP shard) then, respawn-
  side, resets valveState to detent 1 and restores massScale from
  refrigerationFactor.  Mech::Reset now also runs the binary's tail call
  (@0049f788 BTRecomputeCondenserValves) so flow fractions rebuild from the
  reset detents.  Bench: detent 5 -> death -> "[respawn] Condenser1 valve
  detent 5 -> 1".
- #129 SMOKE (real gap, peers-only): the replicant un-wreck edge rebuilt
  the model without the @004d0c14 per-entity effect cleanup, so the
  observer's last 10s wreck-plume window rode the teleport onto the fresh
  mech.  BTStopEntityPfx now runs on the edge; bench shows no plume line
  after any un-wreck until the next death.
- AUTHENTIC (no fix): weapon->generator taps persist (@004b0e6c only
  resolves the link) and MFD display/control modes persist (mapper vtables
  0050f45c/0051e440 slots 8-11 = plain root bodies, read from the exe).
