0.4.0

Added

• Added configurable hash algorithm selection for scans and agents, including optional xxh64 support when the extra dependency is installed.
• Added scanner hash performance controls for worker count and hash chunk size via CLI and environment configuration.
• Added richer large-file scan telemetry, including hashing phase progress and processed-byte reporting.
• Added a local scripts/bench_scan.py benchmark utility plus benchmark guidance in scripts/README.md.

Changed

• Changed scan execution from a fully serialized walk-then-process flow to a pipelined single-host walk/hash/publish model.
• Improved scan responsiveness on warm-cache and medium-tree workloads by overlapping walking, probing, hashing, and publishing.
• Improved running scan telemetry so large-file jobs no longer appear deceptively idle in downstream consumers.

Fixed

• Fixed early Ctrl+C interrupt handling so cancelled scans publish a reliable terminal scan.cancelled event.
• Fixed runtime resolution of CLI hash defaults so settings-based defaults and explicit CLI overrides behave correctly.
• Tightened scanner and CLI regression coverage around multi-worker hashing, hardlink de-dupe, telemetry, cancellation, and hash-option precedence.
