`pi-coding-agent-bun` breaks `nix flake check` in CI: its bun2nix
`fetchBunDeps` calls `builtins.filterSource` on subpaths of the pi.nix
flake source, which requires that source derivation to be realised in the
local store. A fresh CI runner doesn't have it, so eval aborts with
`path '...-source.drv' is not valid`. It only works locally because the
source is already realised there.
Not using pi right now, so comment out the input, overlays, home module
import and the package (leaving a root-cause note in `flake.nix`) rather
than working around the upstream issue.
