- Introduced a new `sync` package for managing NIP-11 relay information and relay group configurations. - Implemented a cache for NIP-11 documents, allowing retrieval of relay public keys and authoritative configurations. - Enhanced the sync manager to update peer lists based on authoritative configurations from relay group events. - Updated event handling to incorporate policy checks during event imports, ensuring compliance with relay rules. - Refactored various components to utilize the new `sha256-simd` package for improved performance. - Added comprehensive tests to validate the new synchronization and group management functionalities. - Bumped version to v0.24.1 to reflect these changes.
