test: permanent V2 checks for airplane (#104) and fastfetch logo (#122)

Move nomarchy-airplane to pkgs/ so checks can import it. checks.airplane
covers the session state machine, menu/keybind surfaces, and whole-swap
waybar parity (mocked nmcli; live radios stay V3). checks.fastfetch-logo
asserts the baked mark is sextant-based with the module flags locked in.
