WAVE 7 Phase A: wire the projectile/missile weapon SUBSYSTEMS byte-exact (un-mislabeled)

Browse Source 
An 8-agent decomp-mapping workflow mapped every weapon-family ctor + fire/spawn path
(scratchpad/wave7_maps.txt).  KEY IDENTITY CORRECTION via VDATA.h enum (base 3000=0xBB8):
the factory ctor-address comments were right but the built CLASS names were stubs/base --
    0xBCD == ProjectileWeapon  (was building the base MechWeapon stub)
    0xBCE == GaussRifle         (NOT MissileLauncher -- was a MissileLauncher stub)
    0xBD0 == MissileLauncher    (NOT BallisticWeapon -- was a BallisticWeapon stub)
Un-mislabeled + wired via Create<Class>Subsystem bridges (mirroring CreateEmitterSubsystem),
each static_assert-locked byte-exact on the now-locked MechWeapon(0x3F0)/Emitter(0x478) bases:

  * ProjectileWeapon (0xBCD, @4bc3fc : MechWeapon, sizeof 0x448)
      FIX: AmmoBinConnection was an empty 1-byte struct -> retyped to the binary's 0xC
           SharedData::Connection (was making the object 8 bytes short, sliding
           MissileLauncher's missileCount off 0x448).
  * MissileLauncher (0xBD0, @4bcff0 : ProjectileWeapon, sizeof 0x44C)
      FIX: deleted muzzleVelocity (ALIAS of inherited ProjectileWeapon launchVelocity@0x410)
           and salvoCount (SHADOW of inherited MechWeapon damageData.burstCount@0x3d4),
           keeping the single own field missileCount@0x448.
  * GaussRifle (0xBCE, @4bdcb4 : Emitter, sizeof 0x484 = Emitter + Vector3D muzzleVelocity)
      DEDICATED bridge (not CreateEmitter): its FireWeapon is a no-op (mov [eax+0x414],0) --
      a non-functional weapon in this 1995 build.  Also fixed GAUSS.CPP's discharge write
      rechargeLevel -> currentLevel@0x414 (the binary writes this+0x414).

Phase A safe-stubs FireWeapon (consume round + recoil, NO spawn): the reconstructed
Projectile (@4be1bc, 0x340) + Missile (@4bf5b4, 0x368) ENTITY classes are NOT spawn-ready
(Entity-base phantom members overflow their New() alloc -> heap corruption; New() takes
(int)this instead of the 0xD4 descriptor; Entity base size unconfirmed 2007-vs-1995, the
Mech 0x638-vs-0x854 problem).  The workflow's adversarial verify flagged the live spawn as a
heap-overflow hazard and recommended exactly this phasing.  Phase B = the entity byte-exactness
+ descriptor build + New(MakeMessage*) so a fired shot becomes a flying entity that damages.

Factory now 18 of 20 cases wired to real ticking classes (remaining: SubsystemMessageManager
0xBD3 [WAVE 8], Gyroscope 0xBC4 [deferred]).  Verified: Mad Cat (LRM/ballistic) + BLH construct
the real weapon classes + tick authentic charge/ammo/heat/recoil, DESTROYED-in-8, 0 crashes,
heapcheck-clean through construction.  Energy weapons already damage via the mech4 beam path,
so combat is unaffected.
