[WIP] Move binaries to additional tools instead of 3rd-party

[Copilot]

Move audio-from-video, data-viewer-audio, and audio-parquet-merger from 3rd-party tools to additional tools

• Update README.md to move the three binaries from "3rd-party Tools" section to "Additional Tools" section
• Update .github/workflows/download-and-release.yml to:
  • Download the three binaries to /tmp/ instead of /tmp/3dparty-bins/
  • Include them in the additional-tools.zip archive instead of 3rd-party-bins.zip
  • Add chmod and strip commands for these binaries
• Verify check_versions.py works correctly with the changes (no modifications needed)
