feat(卡② T6): feats.tres counter_id 改名 + domain/reset_at 键删除 + DO_KEYS 收缩

- twin_digs→adv_twin_digs、instinct_atk→round_instinct_atk（写点+读点 value_counter 成对改）
- 删 9 处 domain/reset_at 键行（含 pain_layers 三处归 battle、insurance_used domain=battle 删键）
- 引擎 DO_KEYS 删 domain/reset_at；do 键白名单注释改前缀归属口径
config_db_test 26 checks 全绿（feats.tres 加载校验通过、跨表护栏零违例）。
