Implements two production-ready Rust native libraries: ## dataset_hash (BLAKE3-based hashing) - FFI exports: ds_hash_file, ds_hash_directory_batch, ds_hash_directory_combined - BLAKE3 hashing for files and directory trees - Hidden file filtering (respects .hidden and _prefix files) - Prometheus-compatible metrics export - Comprehensive integration tests (12 tests) - Benchmarks: hash_file_1kb (~14µs), hash_file_1mb (~610µs), dir_100files (~1.6ms) ## queue_index (priority queue) - FFI exports: 25+ functions matching C++ API - Lifecycle: qi_open, qi_close - Task ops: add_tasks, update_tasks, remove_tasks, get_task_by_id - Queue ops: get_next_batch, peek_next, mark_completed - Priority: get_next_priority_task, peek_priority_task - Query: get_all_tasks, get_tasks_by_status, get_task_count - Retry/DLQ: retry_task, move_to_dlq - Lease: renew_lease, release_lease - Maintenance: rebuild_index, compact_index - BinaryHeap-based priority queue with correct Ord (max-heap) - Memory-mapped storage with safe Rust wrappers - Panic-safe FFI boundaries using catch_unwind - Comprehensive integration tests (7 tests, 1 ignored for persistence) - Benchmarks: add_100 (~60µs), get_10 (~24ns), priority (~5µs) ## Architecture - Cargo workspace with shared common crate - Criterion benchmarks for both crates - Rust 1.85.0 toolchain pinned - Zero compiler warnings - All 19 tests passing Compare: make compare-benchmarks (Rust/Go/C++ comparison)
