Subject: [PATCH] feat: implement parallel build optimization (#2)

- Add MAKEFLAGS=-j24 for parallel make/makepkg
- Add XZ_OPT=-T24 for parallel xz compression
- Fix mkarchiso.sh broken --j$nproc flag (invalid mkarchiso option)
- Clean up build.sh with proper env setup and error handling
- Add PACMAN_OPTS export for consistent overwrite behavior

Closes #2
