Subject: [PATCH] feat: add load_from field for non-system_dir files

Replaces mode: standalone hack with load_from: save_dir on Panda3DS
files. The load_from field documents which libretro directory callback
provides the base path (system_dir default, save_dir, content_dir).
Pack generator and cross-reference skip files not targeting system_dir.
