Introduces a counting semaphore-based throttling mechanism to limit concurrent file I/O and pipeline processing. Replaces custom path wrappers with standardized `Throttled` types across `obikmer` and `obikpartitionner`, ensuring RAII-based resource cleanup and explicit backpressure. Additionally, documents how to redirect Cargo build artifacts to local scratch storage on HPC filesystems to prevent compilation slowdowns.
Replaces the global Rayon pool with per-NUMA-node thread pools that pin worker threads to their respective nodes, leveraging Linux first-touch allocation to reduce cross-NUMA memory contention and improve cache locality. Integrates the `hwlocality` crate with a vendored build, includes graceful fallbacks for single-socket or non-Linux systems, and updates dependency constraints. Also adds installation and architecture documentation, and corrects parallelism detection in the partitioner.
