feedback4: every melee chess whose trait reads 可以放置于远程位 may stand on a 高台, normal or elite, any module

The owner's decision of 2026-10-05 reverses the one of 2026-10-04 (elite 歌蕾蒂娅 with HOK-Y only) and follows PRTS:
the line is the 钩索师 / 推击手 branch trait (歌蕾蒂娅, 崖心, 见行者, normal and elite) and every module keeps it, so
the loadout no longer matters. Raised with the PRTS source in PR #69 by @sunstricken (its own change covered only
歌蕾蒂娅; its test page is not taken). GitHub #153.

- shared/highGround.js: meleeOnHighGround(rec) reads the trait without a module (traitBase, else trait); no module id.
- board.js positionClass(rec) widens those six records; placeClass(ps, rec) = positionClass(rec) for every server
  check (g.move, swaps, merge tile, evictions, audit, invariants). The client's piecePosition mirrors it.
- bot.js: the existing 高台 preference (a 高台 whose range covers the road) now applies to all six; comments.
- Docs: DESIGN §3 and §6.6, DATA (placement), PLAYING §4, META, research 03 C2, code comments. data/ unchanged
  (build-data --offline gives identical files).
- Tests: board, feedback1-placement (each holder with default / no module / every module on each 高台, a 重装
  refused, client highlights, swap, battle, bots), gameLogic.

Golden: 16 scenarios moved, every one because tools/golden.mjs lays operators out by positionClass and now places
歌蕾蒂娅 (normal, or elite with HOK-X) beside the enemy path like a ranged operator instead of on the busiest melee
tile, which shifts the others: roster-010, roster-012, roster-029, roster-040, roster-041; bond-deputShip-high,
bond-indomShip-low, bond-preciShip-low, bond-preciShip-high, bond-suntShip-low, bond-swiftShip-high; boss-boss_2-pair,
boss-boss_4-pair, boss-boss_6-pair, hidden-boss_8-pair, hidden-boss_10-pair. roster-031 (elite with HOK-Y, already
widened) and all matches are unchanged.
