feedback5: merge W5M — the nine 0.1.4 PRs (#150 #66 #146 #74 #72 #103 #149 #109 #160) and W4A (高台 per the trait, 阿戈尔 revive slots, 联防 devour) ported into the split layout

Conflicts: server/match/bot.js (W4A's comment + W5K's player data view pgd), test/golden/diy.json (regenerated). data/ equals an offline build of the merged tools/build-data.mjs. Golden regenerated on the merged code: against feedback5 the moved roster / bonds / fields / matches / standins scenarios are exactly W5M's per-PR attribution (#160 skill events, #109 deploy-timed lifecycle, #66 灵巧 sources and hidden layers, 83fc408 歌蕾蒂娅 placement), plus coop2-NORMAL-70-diy (fields operators those PRs touch) and diy-051 / diy-052 (events.skill only: Misery's deploy passives, #160); against fb5-merge4 only feedback5's own additions (the diy kits, coop2-NORMAL-70-diy).

 // shared/highGround.js — which MELEE chess may stand on a 高台 (a ranged deploy tile).
 //
-// Owner's decision 2026-10-04, reversing DESIGN §22.6. The branch trait 「可以放置于远程位」 is written on
-// every 钩索师 / 推击手 variant (歌蕾蒂娅, 崖心, 见行者, normal and elite) and is not trusted. Only elite
-// 歌蕾蒂娅 carrying module HOK-Y 淡金坠饰 may use a ranged tile. 崖心 (HOK-X only), 见行者, a normal
-// record, any other module, and no module are ground-only. The golden record is the elite (`isGolden`);
-// the same module test applies to it. A missing module id is ground-only.
+// The owner's decision of 2026-10-05, reversing the one of 2026-10-04 (elite 歌蕾蒂娅 with HOK-Y only): follow PRTS. A
+// MELEE chess whose trait reads 「可以放置于远程位」 may stand on a 高台 as well as on the ground. The line is the 钩索师 /
+// 推击手 branch trait (PRTS 歌蕾蒂娅 · 特性, raised with the PRTS source in PR #69 by @sunstricken; PRTS 新人入门: both
+// branches "可部署在高台和地面"): 歌蕾蒂娅, 崖心 and 见行者, normal and elite. It is the branch's own text, not a module
+// effect — every module of the three keeps it — so the loadout does not matter: any module, or none. The text read is
+// the record's trait without a module (`traitBase`, which an elite with modules carries; else `trait`). A module talent
+// such as the 教官's Y module ("可以额外部署在远程位") is a 部署效果, which 卫戍协议 switches off (PRTS 卫戍协议/帮助
+// §战斗部署), and is not read. The battle keeps position MELEE: on a 高台 the unit attacks and blocks nothing.
