chore(build): automate PKGBUILD version updates

This update enhances the build process by ensuring that the package definition file (PKGBUILD) is automatically updated with the current application version and release number. Changes are applied across both local build scripts and CI/CD workflows to maintain consistency. This prevents manual synchronization errors when building releases.

- Updates PKGBUILD version fields using package.json
- Ensures PKGBUILD is staged during final commit in CI/CD
- Improves robustness of the automated build pipeline
