/**
 * Creates an authentication state backed by a generic key-value store (e.g. Keyv).
 *
 * @deprecated The function name is misleading as it no longer uses cache-manager. Use `makeKeyvAuthState` instead.
 * This function is kept as an alias for backwards compatibility.
 *
 * The returned object is compatible with Baileys' `useMultiFileAuthState` / `useSingleFileAuthState`
 * shape and can be passed directly to Baileys when initializing the connection.
 *
 * @param store - The storage backend used to persist credentials and keys. Can be a `Keyv` instance
 * or any `StorageAdapter` implementation exposing `get`, `set`, `delete`, and `clear` methods.
 * @param sessionKey - A unique identifier for the session. It is used as a prefix for all keys
 * stored in the underlying `store` so that multiple sessions can safely share the same backend.
 *
 * @returns An object containing:
 * - `state`: The current auth state with:
 *   - `creds`: The loaded or newly initialized `AuthenticationCreds` instance.
 *   - `keys`: A key store with:
 *     - `get(type, ids)`: Asynchronously retrieves key data for the given `type` and list of `ids`,
 *       returning an object mapping each id to its stored value (or `null` if missing).
 *     - `set(data)`: Persists or removes key data. For each `data[category][id]`, a truthy value is
 *       stored, and a falsy value causes the corresponding key to be deleted.
 * - `saveCreds()`: A function that persists the current credentials (`creds`) to the storage backend.
 *   Call this after Baileys updates the credentials (e.g. inside the `creds.update` event handler).
 * - `clearState()`: A function that clears all stored data. **Important limitation**: This calls
 *   `clear()` on the entire store, which will delete data from ALL sessions if multiple sessions
 *   share the same store instance. This breaks session isolation.
 *
 *   **Recommended solutions for session isolation (prefer option 1 for most use cases)**:
 *   1. Use Keyv with the `namespace` option (one namespace per session) when sharing a backend:
 *      ```ts
 *      const store = new Keyv({ namespace: 'session-1' })
 *      // clearState() will only affect this namespace while still sharing the same underlying store
 *      ```
 *      This is usually more efficient than creating separate Keyv instances because it reuses the same
 *      connection/pool while keeping per-session data isolated.
 *   2. Use separate store instances per session (less efficient than namespaces, but useful if your
 *      storage backend does not support namespacing or similar isolation features).
 *   3. If multiple sessions share one store instance and you cannot use namespaces, avoid calling
 *      `clearState()` and instead clear only the keys that belong to the specific session.
 *
 * @example
 * ```ts
 * import Keyv from 'keyv'
 * import { makeKeyvAuthState } from '@rodrigogs/baileys-store'
 * import makeWASocket from 'baileys'
 *
 * const store = new Keyv('sqlite://auth.db')
 *
 * async function init() {
 *   const { state, saveCreds, clearState } = await makeKeyvAuthState(store, 'session-1')
 *
 *   // Pass `state` to Baileys when creating the socket
 *   const sock = makeWASocket({ auth: state })
 *
 *   // When credentials change, persist them
 *   sock.ev.on('creds.update', saveCreds)
 *
 *   // To fully reset this session later:
 *   // await clearState()
 * }
 * ```
