#124 CORRECTION: aimed hull hits resolve the struck dz_* PANEL -- players were right

The 08-03 zone rule (struck SEGMENT's SKL dzone, ALWAYS -> every aimed
torso hit = center torso) was wrong, and era players' pushback caught it.
Byte-level proof: MAD_TOR.BGF zone-tags the hull PER PANEL (dz_utorso x36,
dz_ltorso/rtorso x18, dz_dtorso x16, all four rear panels, searchlight);
the dpl hit result kept GEOGROUP granularity (dplHitGeoGroup, T0); and the
binary's segment->zone map @49db20 has NO runtime caller (raw call-scan:
sole caller = CreateStreamedDamageZone, load time) -- no segment-level
collapse mechanism exists.  Oracle's night-10 'only LCT gets hits' audit
was the BUG's fingerprint, not the pod's design.

Fix: MechSegmentPick attributes the struck triangle to its draw op (index
range) and takes the op's .DZM-bound zone -- the #87 armour-darkening
bindings, the same authored patch->zone mapping that already paints the
panels -- with the segment dzone as the untagged fallback.  ZoneAimPoint
now aims hull zones at their patch CENTROIDS (all hull zones previously
shared the chest cull-center), which also upgrades the zone walker.

Bench (2-node zone-walk vs spinning madcat, zonewalk_madcat.sh): every
hull panel resolves individually -- utorso 11/12 in-zone, no L/R
mirroring, all four rear panels register; misses are the panel facing the
shooter mid-spin (correct geometry, not misattribution).  Victim applied
254 hits spread across every panel family.  Was 102/102 hull aims ->
dtorso before the fix.
