feedback4: merge master — PRs #150 #66 #146 #74 #72 #103 #149 #109 #160

Golden regenerated on the merged code and attributed by reverting each gameplay PR in a scratch tree: #66 alone moves the fights of roster-008/010/012/022/027/028/031/040, the boss pairs (boss_2/4/6, hidden boss_10) and the matches coop2-NORMAL-3, coop2-HARD-4, coop3-ABYSS-5, coop4-ABYSS-7, solo-HARD-9-boosted (灵巧's aura no longer comes from merchant exits and retreats; hidden-layer bonds keep their internal layers); #109 changes the skill state of its deploy-timed skills (units / hooks / status events / snapshots); #160 adds the 0.5 s skill events of deploy passives (events.skill only in roster-001/006/025/049). The remaining scenarios listed by the full regenerate are those three effects together.
