fix: improve changelog linting to prevent formatting issues (#502)

* fix: improve changelog linting to prevent formatting issues

1. Added a new lint:changelog script to specifically validate the changelog format using auto-changelog
2. Incorporated changelog linting into the main lint and lint:fix processes
3. Updated the lint:misc script to:
- Remove the explicit exclusion of CHANGELOG.md (removed '!CHANGELOG.md'), allowing Prettier to format the changelog alongside the dedicated changelog linter
- Add the --no-error-on-unmatched-pattern flag for more resilient builds
4. Updated GitHub Actions workflow:
- Modified build-lint-test.yml to use our new lint:changelog script
- CI build use the same validation command as local development
- Maintains special handling for release branches with the --rc flag

* chore: reformat `CHANGELOG.md` using new linting configuration

- Apply consistent formatting to establish baseline for future edits
- Remove inconsistent blank lines and standardize section spacing
- Ensure compatibility with both Prettier and auto-changelog validators

* fix: add `prepack` script after accidental removal

* ci: update workflow to use `lint:changelog` script

- Replace direct auto-changelog validate calls with lint:changelog script
- Ensure CI uses same validation command as local development
- Maintain RC validation option for release branches
