/**
 * ActivityLog Repository Interface (Output Port)
 *
 * Defines the contract for ActivityEntry persistence operations.
 * Implementations handle database-specific logic (SQLite, etc.).
 *
 * Following Clean Architecture:
 * - Domain and Application layers depend on this interface
 * - Infrastructure layer provides concrete implementations
 *
 * NOTE: This is an append-only repository per NFR-8 (audit trail immutability).
 * No update or delete methods are provided.
