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.

   - Tokens marked `DEFAULT` in `shopStateTokenDict` are these placeable pieces: 医疗探机, 诅咒娃娃, 狼群, 斯卡蒂的海嗣, 流形. `HIDDEN` tokens exist only in battle.
   - [ASSUMED] Summons do **not** use one of the 8 deploy slots, as in the base game. Keep this as a config flag.
 - **Battle start:** every board unit deploys for free, in order **从上到下>从左到右** (下半): down each column, the columns left to right (research 01 §4.3). In the boss round the order is mirrored for the right-side player. After that, knocked-out units redeploy automatically on their tile when the respawn timer is done and DP ≥ `cost` (DP starts at 10, +1/s, cap 99).
-- **Ranged units may stand on melee tiles** ("所有行动内远程干员可部署在近战位"). Melee units may **not** use ranged-only tiles (HIGH `h`) — except elite 歌蕾蒂娅 carrying HOK-Y 淡金坠饰 (`uniequip_003_glady`).

 ### C3. Pool membership per match
 The per-match ban removes every visible chess whose bonds are **all** in the disabled set. The rule is verified; see 01 Addendum A2. Elites of banned chess are also unobtainable. Hidden chess (17) stay out of the shop as §1.2 says.
