init method

Future<void> init()

--- LIFECYCLE MANAGEMENT --- Initializes the storage engines and triggers code-generated setup.

Timing: This must be called at app startup (e.g., in main or via a DI container like GetIt or Provider).

Flow:

1. Opens SharedPreferences disk handle.
2. Calls initGenerated() to load all stored values into memory.
