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.

 - **Facing (corrected, see research 09 §1.2):** like standard Arknights, every board piece has a direction `dir ∈ UP|RIGHT|DOWN|LEFT` chosen with the 4-direction deploy wheel after dropping it on a tile (also re-orientable in place); default `RIGHT`; persists across rounds. Range grid entries are `[dRow, dCol]` relative to facing RIGHT and are rotated: RIGHT `(dr,dc)`, UP `(dc,−dr)`, LEFT `(−dr,−dc)`, DOWN `(−dc,dr)` (row 0 = bottom); `rangeExtend` applies along +dCol before rotating — to a running skill's range too, unless that skill ignores 攻击距离 (`targeting.noRangeExtend`, 信仰搅拌机 S3, §21.16). The right-side Final Assault player is mirrored col `c→20−c` with RIGHT↔LEFT (UP/DOWN unchanged).
 - **Range test:** an enemy is inside a grid range if the tile containing it (`round(y), round(x)`) is one of the range tiles; a huge enemy (data `hitArea`: 巨型单位, a 4.95 × 2.95 rectangle moved 1.0 up) if any tile its hit rectangle overlaps is one (PRTS 作战机制 "巨型BOSS单位的每一个占据的格子都可以让其本身通过格子判定"; `sim/body.js`, §19.4). Radius ranges (enemies, auras, AoE) use Euclidean distance in tiles — to a huge enemy's rectangle [ASSUMED] — except splash around a struck target, a 中点判定 on positions (PRTS 作战机制 "中点判定…案例：阻挡，酒神1天赋的1.3溅射半径"). A ranged enemy's normal attack takes an ally whose collider (radius 0.25, PRTS 作战机制 §碰撞体积 "我方干员碰撞体积基本均为以0.25格为半径的圆形") touches its range circle: centre distance ≤ `rangeRadius` + 0.25 (`constants.js ALLY_COLLIDER_RADIUS`, `ai.js enemyAttack`; §20.4).
 - **Fields at runtime:** a `Battle` receives a **field rect** (rows/cols subset) and the full stage grid. Normal battles use rows 9–12 × cols 0–10; unite uses rows 9–12 × cols 0–20; boss uses rows 0–5 × cols 0–20 (solo boss uses the left half only). Pathfinding never leaves the rect.
