/**
 * Local structural types for the optional @juspay/hippocampus integration.
 *
 * These mirror the public shapes that ship with @juspay/hippocampus's
 * `dist/types.d.ts` so NeuroLink's public type surface stays compatible
 * for consumers that already configure memory, while the runtime package
 * itself becomes an optional peer dependency. The previous setup (a hard
 * value import of @juspay/hippocampus) made pnpm pull a registry copy of
 * @juspay/neurolink to satisfy Hippocampus's peer, which transitively
 * dragged @ai-sdk/google + @ai-sdk/google-vertex into the production
 * dependency graph.
 *
 * Naming:
 *  - Hippocampus's own `StorageType` and `RedisStorageConfig` collide with
 *    NeuroLink's in-house Redis manager types in `common.ts` /
 *    `conversation.ts`. To satisfy the `unique-type-names` ESLint rule,
 *    the storage variants get a `Memory*` prefix here.
 *  - `HippocampusMemory` (consumer-facing) and `StorageConfig` (legacy
 *    re-export) keep their original public names — only their definitions
 *    move from `import("@juspay/hippocampus").Foo` to local structural form.
