Bumps core dependencies including ndarray, rand, hashbrown, niffler, ureq, sysinfo, indicatif, lru, and remove_dir_all. Adapts source code to accommodate breaking changes by migrating RNG initialization, adjusting HTTP response handling, and replacing the fs4 crate with standard library file locking. Adds a planning document for query benchmarking and sparse index regression tests.
Introduces raw mapping and iteration APIs that bypass membership checks, clarifies variant-specific storage layouts and auto-detection logic, and documents optimized batch access patterns with caller-provided buffers. Removes the outdated obicompactvector_reflexion.md specification to consolidate architectural details into current implementation docs.
