These four recipes applied their local/patches/ at build time via
cookbook_apply_patches — a helper that is NOT defined in the cook environment
('command not found', aborting the build on pipewire). Per the full-fork vendored
model, bake each recipe's patches into its committed source/ (redox compat shims,
qnetwork impl, kf6 migration) and remove the broken call. The .patch files stay
tracked in local/patches/ for version-bump re-derivation.
