fix(packaging): use version from spec file for RPM builds

- Update Makefile to extract PKG_VERSION from spec file
  Reads '%define spec_version 1.0.2' as default version
- Update spec file with proper version macro logic
  Version field now uses %{spec_version}
  Supports override via --define 'build_version X.Y.Z'
  Falls back to 1.0.2 when build_version is not defined

This ensures RPM packages are built with the correct version
defined in the spec file (1.0.2) instead of hardcoded 1.0.0.
