 * MAMA Core API initialization.

 * Responsibilities:
 *   1. Dynamically require mama-core (initDB, getAdapter, mamaCore)
 *   2. Wire up connectorExtractionFn through the configured backend (lazy-init + lifecycle)
 *   3. Normalize the MAMA API shape into mamaApi
 *   4. Build search() / searchForContext() wrapper functions with fallback handling
 *   5. Build loadCheckpointForContext / listDecisionsForContext wrappers
 *   6. Assemble and return the mamaApiClient object
