**feat(scripts): add automated release workflow script**

- Introduced `release-workflow.js` to streamline the release process:
  - Automates version updates (`patch`, `minor`, `major`).
  - Generates changelogs based on commit messages.
  - Creates GitHub releases with autogenerated notes.
  - Publishes packages to NPM.
- Enhanced documentation in `README.md` with detailed release instructions, both automated and manual.
- Updated related test cases and ensured compatibility.

**Purpose**: Simplify and standardize the release
