/// Unified error type for Codemem.
///
/// Variants like `Storage(String)` intentionally carry a stringified error
/// message rather than the original typed error. This avoids coupling
/// `codemem-core` to storage-specific dependencies (e.g. `rusqlite`),
/// keeping the core crate lightweight and backend-agnostic.
