commit ef933162261ea7b90975199ee7c1a53cf004a10b

    feat: shallow sparse clone instead of full kernel mirror
    
    makepkg hardcodes git clone --mirror with no depth/filter/sparse
    support, pulling ~2.75 GB for the full kernel tree. Handle the
    clone manually with --depth=1 --filter=blob:none --sparse, fetching
    only fs/bcachefs and include (~92 MB).
    
    Switch pkgver to date-based format (works with --depth=1).
