          Merging this PR will:
          - Update package versions in \`src/frontend/package.json\`, root \`package.json\`, and \`pyproject.toml\`
          - Update \`CHANGELOG.md\` with the changes
          - Update \`.vscode/launch.json\` dev version

          Once merged, a release tag (\`v${{ steps.changesets.outputs.version }}\`) will be created automatically, triggering the DMG and Linux release builds."
