Erik 156dc453c9 docs(register): AP-35 drop false equivalence; AP-16 retarget to per-object/cell 8-light cap — A7 Fix D
AP-35: the "numerically equivalent" claim was false. Residual is now two
parts: (a) per-frame GPU evaluate vs retail's bake-once (architecture/perf
difference only; formula matches), and (b) SelectForObject 8-cap means a
surface reached by >8 point lights is dimmer than retail's uncapped bake.
Cross-references AP-16 for the cap ownership.

AP-16: the old "global nearest-8 viewer-distance into UBO" description was
stale — the UBO point-light path is now vestigial (mesh_modern.vert skips
posAndKind.w!=0 entries; point lights come exclusively from the per-object
SSBO binding 5). Retargeted to the current SelectForObject per-object/cell
8-cap mechanism with correct file:line (LightManager.cs:234), both call
sites (ComputeEntityLightSet + GetCellLightSet), and the retail oracle
distinction (hardware cap 0x0054d480 faithful; bake 0x0059cfe0 not).
Preserved the UBO-directional-only note inline rather than losing it.
