fix(zone-cold): JSON_MERGE_PATCH 原子寫入 + JSON_REMOVE 原子刪除（B2）
set()/set_many() 原本 get_blob_raw()→array_merge→save_blob() 三步，並發
寫入會互相覆蓋整個 blob；remove() 同樣是 read-modify-write。改為：
- 新增 private save_patch()：INSERT ... ON DUPLICATE KEY UPDATE
data = JSON_MERGE_PATCH(COALESCE(data,'{}'), patch)
- remove()：UPDATE ... SET data = JSON_REMOVE(COALESCE(data,'{}'), '$.key')
- save_blob() 改用 TMDO_DB::upsert()
- SQLite 保留 read-modify-write fallback
- ZoneColdTest stub 補 JSON_REMOVE / JSON_MERGE_PATCH / upsert 三種 SQL 模擬
對應 A v3.3.3 P1-21。unit 379 / integration 398 GREEN
