 		perf: add profiling benchmarks and parallel Go baseline for C++ optimization 
Add comprehensive benchmarking suite for C++ optimization targets:
- tests/benchmarks/dataset_hash_bench_test.go - dirOverallSHA256Hex profiling
- tests/benchmarks/queue_bench_test.go - filesystem queue profiling
- tests/benchmarks/artifact_and_snapshot_bench_test.go - scanArtifacts/extractTarGz profiling
- tests/unit/worker/artifacts_test.go - moved from internal/ for clean separation

Add parallel Go implementation as baseline for C++ comparison:
- internal/worker/data_integrity.go: dirOverallSHA256HexParallel() with worker pool
- Benchmarks show 2.1x speedup (3.97ms -> 1.90ms) vs sequential

Exported wrappers for testing:
- ScanArtifacts() - artifact scanning
- ExtractTarGz() - tar.gz extraction
- DirOverallSHA256HexParallel() - parallel hashing

Profiling results (Apple M2 Ultra):
- dirOverallSHA256Hex: 78% syscall overhead (target for mmap C++)
- rebuildIndex: 96% syscall overhead (target for binary index C++)
- scanArtifacts: 87% syscall overhead (target for fast traversal C++)
- extractTarGz: 95% syscall overhead (target for parallel gzip C++)
