KB: reconcile the context system with the day's work

- decomp-reference.md: the binary ATTRIBUTE-TABLE section -- 16-byte
  {id,name,off+1,0} row format (alignment warning), the walker technique,
  and the three recovered tables (Mech ids 21-56 incl the corrected
  EyepointRotation@0x360 / RearFiring@0x410 / DistanceToMissile@0x400
  labels; HeatSink 3-12; Torso 3-15; the weapon RearFiring 'b' marker).
- combat-damage.md: the REAR-FIRE + look-view system (roster survey: the
  Blackhawk's ERMLaser_2/3 are the game's only rear weapons; every missile
  rack forward), the missile mount-frame launch truth, and the BANKED
  full Missile flight-model decode (three performances, proximity fuse).
- wintesla-port.md: post-Phase-4 closures (instability model live, F14
  static filter baked, the footstep warm-up bug + its trace-cap lesson);
  deferred list trimmed to F21/HRTF.
- AUDIO_FIDELITY.md: status block -- F14 FIXED, warm-up bug noted.
- open-questions.md: "which mechs used rear fire" answered from data;
  remaining look-view key bindings noted.
checkctx: CLEAN.
