refactor: Combine all workflows into single main CI/CD pipeline

- Merge 4 separate workflows into one unified pipeline
- Step-wise execution:
  1. Tests run automatically
  2. Coverage check for new functions
  3. Version detection from package.json
  4. Tag creation (if doesn't exist)
  5. Minified file generation
  6. Release package creation
  7. Git tag push
  8. GitHub Release creation
- Fully automated - triggers on push to main
- Removed separate workflows: ci.yml, test-coverage-check.yml, auto-release.yml, release.yml
