merge: absorb samwhosung/main on top of the upstream merge

Same fork policy: upstream structure wins, local-unique re-instated.

Cargo.toml unions both measured dev-profile philosophies (codegen-units=1 +
lto=off from samwhosung, debug=line-tables-only + split-debuginfo from the
fork's disk measurements).

glue_booth.rs takes samwhosung's typed GlueScene (token/of_race/from_model_path)
and re-adds the fork's TurtleWoW races (Goblin=9, BloodElf=10) as variants;
their glue fog stays on Human's row, exactly as the fork's scene_fog fallback did.

ui script takes samwhosung's mouseover/hyperlink rework (world_mouseover,
minimap_blip, hyperlink.rs) over the fork's inline hover_link/span_at/pointer
path — the rework covers the same OnHyperlinkEnter/Leave behaviour.

game_plugins.rs keeps the fork's re-measured ceilings (466 / 5,509); mail.rs
keeps the explicit 13-tuple with a float daysLeft; MAP.md takes the superset.
