#124: hit-location ASPECT was rotated 180 degrees -- the resolver now speaks the 1995 frame

Browse Source 
Night-10's systematic targeting audit (rear panels unhittable from
direct fire, Owens left torso hitting the RIGHT weapon pod and vice
versa, missiles favoring the far side) measured down to one geometric
fact: the authored wedge ring puts the Front* cells in the +Z arc
(slice-name audit, bit-verified tables), i.e. the 1995 resolver frame
has mech-forward = +Z -- while OUR engine's entity frame carries
forward along -Z. Bench proof: a victim facing its attacker took
frontal beams at local z = -4..-10, theta ~270 deg, resolving the
REAR-named cells (zones 12/14/15) every time.

The two frames differ by a pi ROTATION about Y -- rotation, not
reflection, because the field flank observations CROSS (left->right)
rather than persist. ResolveHit now rotates the local impact into the
cylinder's frame (negate x and z; y untouched; handedness preserved so
the SelectSlice torso-twist add keeps its sign).

A/B (172 resolves, live missiles+beams on a facing victim): before
theta~4.7 -> rear zones only; after theta~1.42-1.59 -> utorso/dtorso/
ltorso/rtorso/arm -- the front-authored cells, with the per-burst
re-roll scatter intact.

NOT this bug: the "one band LOW" Y-axis half of the night-10 table --
that is #16 (pick-ray boresight parallax, code-confirmed, still open).
