commit 78343984a6699d6dcaf5e561c6e72887fee5bf3b

    phase1: apply feeds_host_override to main repository URL
    
    When feeds_host_override is configured, also apply it to the main
    OpenWrt repository URL (repo_url). This fixes git fetch 503 errors
    when git.openwrt.org is overloaded by redirecting to GitHub mirror.
    
      git fetch -f -t https://git.openwrt.org/openwrt/openwrt.git main --progress
      error: RPC failed; HTTP 503 curl 22 The requested URL returned error: 503
      fatal: the remote end hung up unexpectedly
