Mech: THE 0xBD3 UNTANGLE -- real SubsystemMessageManager in [0x10d], the mapper's one true home is roster slot 0 (task #7)

Browse Source 
Binary census [T1]: mech+0x434 has exactly 2 writers (ctor init + factory
case 0xBD3) and ONE reader (@0x4b984b in MechWeapon::SendDamageMessage
@004b9728) -- pure message-manager semantics, nothing mapper-like.  The
factory case now builds the real SubsystemMessageManager (ctor @0049bca4,
0x130, ConsolidateAndSendDamage Performance); the misbuilt MechControlsMapper
squatter is evicted.  Every mapper consumer re-pointed to MappingMapper()
(roster slot 0 = the binary's **(mech+0x128); SetMappingSubsystem @0049fe40
touches ONLY slot 0 -- its [0x10d] mirror removed).  Non-viewpoint mechs get
a slot-0 demand LATCH (base mapper, [T3] accommodation -- the binary leaves
slot 0 NULL off-viewpoint but never drives/animates those paths; ours does).
Verified: solo drive+gait clean; MP replicant gait through the latch (full
run lifecycle); 3x kill/respawn cycle with type-6 records on the observer.
Remaining (task #7 tail): the messmgr's consolidated TakeDamageStream send +
weapon-path routing (@004b9728 real body).
