Never-committed working tree state found in the dev worktree: a Pi 4 hardware module, a setup walkthrough, an upboard-serial refactor, and flake wiring that does not evaluate (aarch64 packages block nested inside packages.x86_64-linux; pkgs-aarch64 built with `inherit aarch64` instead of `system`, so it is really x86; references a nixosConfigurations.rpi4-installed that is never defined). Parked verbatim for reference. The real Pi 4 target is rebuilt on top of #87's mkPiInstalled/mkPiImage shape in feat/rpi4-target.
