Audio Phase 4a (AUDIO_FIDELITY F6/F7): coolant-leak warning + missile alarm

Browse Source 
F6 ReportLeak (the largest dead authored block -- 38 of 54 match watchers):
recovered the binary HeatSink attribute table (16-byte {id,name,off+1} rows
@0x50e438..0x50e4c8, ids 3..12) [T1] -- it confirms EVERY existing heat
binding (CurrentTemperature@0x114 .. CoolantMassLeakRate@0x130, HeatSink@
0x164) and adds the one row we never published: ReportLeak (id 12) ->
+0x138 = coolantActive, the INT leak hysteresis flag UpdateCoolant
(@004adbf8) drives 1/0 around draw 0.003/0.0025.  PoweredSubsystem derives
from HeatSink, so the single row serves all 19 authored leak watchers
through the chained index, exactly like the binary.  MechWeapon's pinned-id
pad absorbed the +1 chain shift (0x0E -> 0x0F, tripwire fired as designed).

F7 IncomingLock/DistanceToMissile (missile alarm): binary Mech table walked
in full (ids 21..56 [T1] -- also settles FootStep@0x394, CollisionSpeed@
0x4B4, UnstablePercentage@0x3F0, ReduceButton@0x340 for the next findings).
IncomingLock id 54 @0x3fc, DistanceToMissile id 56 @0x400; the old
"maxSpeed @0x400 = FLT_MAX" member was a MISREAD of the far default and is
retired (its 1000.0f "override" was RadarRange id 47 @0x404, already
published).  Real members + accumulators: Missile::MoveAndCollide reports
target + range each tick (BTReportIncomingMissile bridge); PerformAndWatch
latches per frame.  The authored beeper (match 1/0) + range->TEMPO scale
(100..800 -> 600..10, accelerating as the missile closes) read them
unchanged.  Drive is intent-level [T3]; init 0/FLT_MAX matches the binary
reset (part_012.c:9446-9447).

Regression (30s): stable; ReportLeak binds real on every subsystem (0 pad
redirects); DistanceToMissile binds with FLT_MAX live; attrnull 41 -> 3.
