feedback5: merge W5H — 自选 data (72 owned 6★ without the 6 collab operators, every DIY form, summons, prototypes' locked skills), shared/diy.js, the sim fields DIY picks, OPERATOR_KIT_FILES with 推进之王 as the first operator kit, golden family diy, the art plan (--add-only)

Conflicts: tools/golden.mjs / test/golden/README.md take both new families (standins from W5G, diy from W5H); DATA.md / SIM.md keep both texts. data/ equals an offline build of the merged tools/build-data.mjs. Golden regenerated on the merged code: against feedback5 nothing moved, diy.json is new; against fb5-diy the W5G / W5J / W5L scenarios moved, and diy-004 / diy-006 (the prototype battles with Touch, changed by W5L) — diy-001/002/003/005 identical.
