feedback5: merge CB5 — community reports (match / UI): module 特性追加 shown after the base trait (text only), a shop upgrade fills its new slot at once, spectators follow the player they picked through every phase (g.watch carries the playerId — PR #189's idea), the boss shows in boss-round prep scouting, the final-boss prep shows the pair together with green avatar frames (PR #191's idea, official colour); §25.19 after the hotkeys' §25.15; golden: the 18 bot matches (the upgrade's new card), battles unchanged
