docs(issues): #37 — Investigation 2 narrows bug to SubPalette coverage gaps

Browse source 
Five parallel agents + dat probes ruled out:
- byte-level decode primitive (matches ACViewer)
- polygon emission (no ST_DOUBLE / Surface.Type & 6 issues)
- per-PART texture-override scoping (correctly per-MeshRef'd)
- SubPalette indexing convention (full-size 2048 palettes, *8 wire un-pack
  is single-applied)

Smoking gun: for +Acdream the server sends 10 SubPaletteSwap ranges that
overlay palette indices [0..320), [576..1024), [1392..1488), [1728..1920).
The complement — [320..576), [1024..1392), [1488..1728), [1920..2048) —
is NOT overlaid. Base palette 0x0400007E at those indices has
red/skin tones. Coat texture UVs sampling those non-overlaid indices
render as visible "skin stub at top of coat".

Either ACE sends incomplete SubPaletteSwap data, or retail does extra
client-side ClothingTable computation we (and ACE) don't.

Diagnostic harness now lives at tools/InspectCoatTex/Program.cs;
GameWindow's DUMP_CLOTHING also probes runtime SubPalette dat sizes.
