feedback5 WM: merge feedback4 at 13808e3 (W4A) — 高台 for every 「可以放置于远程位」 trait holder, the 5-阿戈尔 revive slots, the 联防 devour of whoever stands in front

Ported by hand into the split layout:
- 83fc408 board.js placeClass: the player's loadout no longer counts, as in 83fc408. feedback5's 补位 rule stays: a
  chess the player fields as its stand-in is placed by the stand-in's record (ps.fieldRecord). positionClass(rec)
  takes no module.
- 83fc408 client piecePosition → public/js/ui/gameLogic/placement.js: meleeOnHighGround(rec) on the stand-in or
  chess record, no module. The gameLogic.js shim header and deployedModuleId's comment follow; deployedModuleId is
  kept, still exported and tested.
- 83fc408 PlayerState._placementOf comment → server/match/player/placement.js.
- 83fc408 tools/golden.mjs layout: positionClass without the module, on feedback5's stand-in body (recOf) and in
  diyLayout.
- bonds/core.js (6ab9a06, 8a2e0c7) applied cleanly; it equals 13808e3's plus feedback5's i18n toast. shared/highGround.js
  equals 13808e3's.
- data/: only bonds.json (the 阿戈尔 spec text). node tools/build-data.mjs --offline on the merged tree rewrites all
  15 files byte-identical.

Golden regenerated: 16 scenarios moved, all by 83fc408. Each fields 歌蕾蒂娅 (normal, or elite with HOK-X / no
module), whom tools/golden.mjs now lays out beside the enemy path like a ranged operator instead of on the busiest
melee tile: 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. This is the list in 83fc408's own message. With the
阿戈尔 commits reverted the digests are the same, so those two move nothing in this corpus. The standins, diy and
matches families are unchanged: no stand-in or 自选 piece there is 歌蕾蒂娅, 崖心 or 见行者.
