Initial commit

Pinned OpenWrt feed hashes for realtek/rtl930x on snapshot and 25.12.5, generated with nix-openwrt-imagebuilder's release2nix. Expanding the feeds locally (rather than relying on upstream's index-level hashes) keeps every package a plain pinned fetchurl, and removes the import-from-derivation that would otherwise make evaluation depend on the OpenWrt download server.
