Camera seat LIVE + Mech::PlayerLinkMessageHandler reconstructed (@0049f624)

Browse Source 
The spectator/broadcast seat works end-to-end: a hostType=1 +
vehicle=camera pilot page boots a CameraShip whose 62-camera arena1
network loads from the BTL4.RES type-27 resource (the engine's
CreateStreamedCameraInstances existed all along -- the file probe falls
back to it), the BTCameraDirector locks onto the first live mech, and
the ship TRACKS it (sees=1, goal advancing) and CUTS between authored
camera positions (screenshot-verified: wide arena shot -> close
tracking shot).

The missing piece was the Mech override of PlayerLinkMessageHandler
(@0049f624), which the reconstruction never filled.  The engine base
resolves mech->player; BT's override adds:
  1. the REVERSE link player->playerVehicle = this on EVERY node
     (replicants included) -- how the camera director and scoreboard
     find a REMOTE player's mech; without it a spectator parks forever
     ('NO goal entity')
  2. clears NonScoringPlayerFlag (0x4000 = bit 14): a pilot with a
     vehicle is a SCORING player -- this admits REPLICATED players to
     the ranking pass, so cross-node rank/score displays work
  3. master only: seeds the heat bank's ambientTemperature (bank
     @0x1d4) from the mission [mission] temperature= (BTMission+0xf4)
     -- correcting the heat family's 'frozen 300' deviation note (it
     was never frozen; THIS is the writer)

Bridge BTSetBankAmbientTemperature lives in heatfamily_reslice.cpp
(mech.cpp cannot include subsystem headers -- local-stub collision).
BT_CAM_LOG diagnostics: camera-network count, director pick + Players
group census, ship follow state, link dispatch/receive.

Verified live: 2-seat (mech + camera) relay session -- replicated
player shows +veh, director goal locked w/ 30s timer, ship tracking a
moving mech through camera cuts; standard 2-node mech smoke PASS
(un-regressed).  Lesson re-learned: a 'clean' build filtered on 'error
C' missed a linker file-lock failure -- one whole test cycle ran
against a stale exe (the /FORCE gotcha's cousin; grep -i error, not
error C).

Remaining (task open): ranking-window overlay draw (L4VIDRND stubs),
operator-app camera-seat row, shot polish.
