refactor(types): 消除非必要 as 逃逸，锁紧 strict 政策

按 Oracle 复核处置全仓 5 处类型断言：

- fields.ts: as const → satisfies Record<GeneratedFieldKey, true>
- compile.ts: as readonly string[] → ReadonlySet<string>.has()
- embed-migrations.ts: JSON.parse as Journal → Zod schema 运行时校验，JSON.parse 显式 unknown
- interceptors.ts: 唯一保留的跨包断言（ORPC→Zod）注释扩写为完整背景
- router.tsx: satisfies 非 cast，保留

biome.json 增配 noExplicitAny / noTsIgnore / noNonNullAssertion，防止后续漂移。
