Summary

Bump scale-nucleus from 0.18.3 to 0.18.4 and add a CHANGELOG.md entry for the local pHash deduplication utility merged in #462.

This follows the prior release metadata pattern from #461 and #455: update the single Poetry version source in pyproject.toml, then prepend the matching Keep-a-Changelog entry.

Release notes

• Adds release metadata for deduplicate_by_phash, which deduplicates DatasetItem objects or items_and_annotation_generator() rows by local pHash without API calls.
• Documents threshold support and the returned result fields (unique, unique_dataset_items, unique_reference_ids, and DeduplicationStats).

Validation

• poetry run pre-commit run --all-files
• poetry build
• Verified scale-nucleus latest on PyPI is currently 0.18.3; v0.18.4 is not present in local tags.

After this merges, publishing should be triggered by tagging the merged commit as v0.18.4.
