71 upstream commits: the repo-wide comment rewrite, the hover highlight as the
scene ambient, M2 Mod/Mod2x batches drawing the bare texel, test and contribution
changes. Conflicts were comment-vs-code in 36 files; where upstream changed only
comments our code was kept, and wow_model.wgsl carries both our lighting lanes
and upstream's new unlit/Mod/Mod2x paths.
Follow-ups folded in:
- our nine Advanced Graphics / water / fog options tests take upstream's
wow_data_or_skip! guard
- PostUpdate ambiguity ceiling re-measured under upstream's new census: 466,
with the per-family breakdown in the comment
- LIGHTING.md: new upstream base

Water (Enhanced/High; Classic stays byte-identical to upstream):
- the enhanced water now lives in its own WGSL library, benilla::enhanced_water
(enhanced_water.wgsl), with its own bindings 103-106; upstream liquid.wgsl
keeps three small hooks only
- depth look: per-channel extinction over the real path through the water,
refraction of an opaque-colour copy bent by the waves (samples landing on
anything in front of the water are refused via the scene depth), caustic
web on sunlit shallow beds
- High: screen-space reflection of the scenery (bisected march against the
scene depth)
- the module fogs its own surface terms only (the refracted/reflected scene is
already fogged); depth+colour copies run both-or-neither
- credits: portions derived from WarcraftXL wxl-experimental-water by
iThorgrim, used with permission (WATER.md)
Volumetric fog (Advanced Graphics -> Volumetric Fog: Off/Low/High, cvar
volumetricFog, env WOW_VOLFOG): own fullscreen pass after the main pass,
near-field haze converging on the zone fog colour, denser at dawn and in
weather, faint indoors, plus sun/moon light shafts from the shadow map.
Tests: addon-harness oracle fixtures no longer require unix symlinks.

Drops the Everwood-specific fork bits (realmd split-build constant, fork catalogue, local
ignore rules) so this branch is upstream 66388278 plus lighting, and adds LIGHTING.md.
