native: security hardening, research trustworthiness, and CVE mitigations
Security Fixes:
- CVE-2024-45339: Add O_EXCL flag to temp file creation in storage_write_entries()
Prevents symlink attacks on predictable .tmp file paths
- CVE-2025-47290: Use openat_nofollow() in storage_open()
Closes TOCTOU race condition via path_sanitizer infrastructure
- CVE-2025-0838: Add MAX_BATCH_SIZE=10000 to add_tasks()
Prevents integer overflow in batch operations
Research Trustworthiness (dataset_hash):
- Deterministic file ordering: std::sort after collect_files()
- Recursive directory traversal: depth-limited with cycle detection
- Documented exclusions: hidden files and special files noted in API
Bug Fixes:
- R1: storage_init path validation for non-existent directories
- R2: safe_strncpy return value check before strcat
- R3: parallel_hash 256-file cap replaced with std::vector
- R4: wire qi_compact_index/qi_rebuild_index stubs
- R5: CompletionLatch race condition fix (hold mutex during decrement)
- R6: ARMv8 SHA256 transform fix (save abcd_pre before vsha256hq_u32)
- R7: fuzz_index_storage header format fix
- R8: enforce null termination in add_tasks/update_tasks
- R9: use 64 bytes (not 65) in combined hash to exclude null terminator
- R10: status field persistence in save()
New Tests:
- test_recursive_dataset.cpp: Verify deterministic recursive hashing
- test_storage_symlink_resistance.cpp: Verify CVE-2024-45339 fix
- test_queue_index_batch_limit.cpp: Verify CVE-2025-0838 fix
- test_sha256_arm_kat.cpp: ARMv8 known-answer tests
- test_storage_init_new_dir.cpp: F1 verification
- test_parallel_hash_large_dir.cpp: F3 verification
- test_queue_index_compact.cpp: F4 verification
All 8 native tests passing. Library ready for research lab deployment.

feat(cli): Add core infrastructure for local mode support
- mode.zig: Automatic online/offline mode detection with API ping
- manifest.zig: Run manifest read/write/update operations
- core/: Common flags, output formatting, and context management
- local.zig + local/: Local mode experiment operations
- server.zig + server/: Server mode API client
- db.zig: Add pid column to ml_runs table for process tracking
- config.zig: Add force_local, [experiment] section with name/entrypoint
- utils/native_bridge.zig: Native library integration
