/**
 * EphemeralBaseAccountProvider is a provider designed for single-use payment flows.
 *
 * Key differences from BaseAccountProvider:
 * 1. Creates its own isolated store instance (no persistence, no global state pollution)
 * 2. Uses EphemeralSigner with the isolated store to prevent concurrent operation interference
 * 3. Cleanup clears the entire ephemeral store instance
 * 4. Optimized for one-shot operations like pay() and subscribe()
 *
 * This prevents:
 * - Race conditions when multiple ephemeral payment flows run concurrently
 * - KeyManager interference (each instance has its own isolated keys)
 * - Memory leaks (store instance is garbage collected after cleanup)
