HUD ironing (task #38): authentic Lock producer + simple-X mode

Browse Source 
- LOCK rules transcribed from the exported HudSimulation
  (part_013.c:5619-5634): lock requires a target AND your own HUD host
  zone damage < 0.75 (_DAT_004b7ec4 -- a shot-up targeting computer
  drops lock) AND the targeted zone damage < 1.0 (_DAT_004b7ec8;
  whole-mech target checks zone 0 -- a wreck's dead zone can't
  re-lock). Box and ring are now separate signals like the binary:
  gBTHudLockState 1 = target held (hotbox draws), 2 = LOCKED (+ the
  spinning ring).
- SIMPLE-X mode: the ctor's [0x99] minimal-reticle list transcribed
  (@4689-4705: green +-0.02..0.08 cross on the aim translate); Draw
  switches master <-> simple X on the PrimaryHudOn element bit (0x20),
  completing the recovered Execute's state-list logic.
- Canopy diagnosis sharpened (open-questions): blx_cop is the torso
  segment's inside-skeleton mesh enclosing the eye; the black box =
  the skeleton render branch missing its texture + PUNCH cutout (the
  canopy windows are punch texels). A rendering-branch task; stays
  hidden by default.
