refactor(迭代35卡②T2·一口): 跨表校验④「关卡节点→敌/板覆盖与多终点 Boss 共带」随静态节点数据消亡整体退役——两条拦截语义改由运行时断言承接：顶 clamp 消解禁＝〔v11〕「解析落带 ≥ 请求深度」、多终点 Boss 带键互异＝〔v11〕逐终点带键两两比对（拦截面从表内静态代理升级到消费图本体，无削弱）；其单测段 _test_level_node_band_rules 与随它而存的四个 preload 一并退役（fv15/fv16/fv17 三条判据的现役等价面在 level_shop_economy〔v11〕与 level_table_validate〔v1〕）

- 覆盖不降级的依据：生成图深度域实测 L1 0–6／L2 0–9／L3 0–13 为模板池深度域（0–4／0–9／0–9）的超集，且 〔v11〕扫描面三档×20 种子逐节点核敌带与板精确行
- save_manager 首次冒险位注释随确定性承载换代改口径（首局固定种子 42＋参数档生成图，无兜底模板），键与行为零改动
- run_all 59 套件全绿
