There appears to be duplicate changelog entries for version 0.82.3 in the minify and parser NAPI packages. Each package has identical entries repeated twice, which creates unnecessary redundancy in the changelog.

For better documentation clarity, please remove the duplicate entries to maintain a clean changelog history. This affects:

1. napi/minify/CHANGELOG.md - duplicate entries for 0.82.3
2. napi/parser/CHANGELOG.md - duplicate entries for 0.82.3
3. napi/transform/CHANGELOG.md - duplicate entries for 0.82.3

This duplication likely occurred during the changelog generation process.
