feat: add PersistentBitVec and upgrade PersistentCompactIntVec format

Introduces PersistentBitVec, a dense, memory-mapped bit vector optimized for bulk u64-word operations and SIMD acceleration, complete with bitwise operators and Jaccard/Hamming distance metrics. Upgrades PersistentCompactIntVec to a unified .pciv format using 64-bit indices and offsets, consolidating the binary layout and updating builder/reader lifecycles accordingly. Adds corresponding documentation, updates MkDocs navigation, and implements a comprehensive test suite for persistence round-trips, edge cases, and metric accuracy.
