- Added `from_slice` method to `CacheBlock` for creating instances directly from slices, avoiding unnecessary allocations. - Introduced `write_data` method in `CacheBlock` to allow in-place updates of block data. - Updated `insert_one_block` and `immediate_write` methods in `BlockCache` to accept slices instead of vectors, improving performance and memory usage. - Implemented error handling for block size validation in multiple locations to ensure data integrity. - Change `FileMapInfo::page_cache` to `Weak<PageCache>` to fix a memory leak caused by reference cycles.
