v1.0.0

Added

• Unified configuration API with vsort_options_t, feature flags, and result codes
• New vsort_sort entry point plus helpers to query and set default behaviour
• Stable merge sort mode and counting sort fast path for byte arrays
• Parallel introsort pipeline with chunked merging on Apple Silicon devices

Changed

• Replaced legacy quicksort driver with adaptive introsort + heapsort fallback
• Refactored runtime into a calibrated hardware profile with thread-safe init
• Simplified radix sort guardrails and nearly-sorted detection heuristics
• Default parallel and radix policies now configurable per-call

Fixed

• Prevented radix overflow on very large integer ranges
• Guaranteed deterministic comparator handling for generic dispatch
• Eliminated redundant memory allocations in merge passes
