feat(model-specs): 新增模型规格库——跨 provider 模型参数统一维护（presetDataVersion 54→58）

* feat(model-specs): 新增模型规格库与 schema 契约

- compute/model-specs/：按厂商维护模型内在参数（上下文窗口/最大输出/能力/serviceType/默认温度，不含价签）
- schemas/model-spec.schema.json：Draft-07 契约，spec 允许 null（新文件不影响老客户端 frozen 契约）
- scripts/validate.mjs：pickSchemaKey 纳入 model-specs 校验
- manifest.presetDataVersion 54→55

* feat(model-specs): 新增小米 MiMo 系列模型规格；bump presetDataVersion 55→56

* feat(model-specs): 补全全量模型规格；presetDataVersion 56→57

* feat(model-specs): 新增 releasedAt/retiredAt 时间戳字段；补充 mimo 退役日期
