Mount retroarch/shaders and retroarch/overlays from the game drive into
~/.config/retroarch/{shaders,overlays} for both ES-DE and standalone
RetroArch (sibling to the existing cores mount). Anything pulled from the
Online Updater or set in the Quick Menu now persists across sessions and
survives a Wolf/OS reinstall, so a CRT shader or bezel set is configured
once. Dirs are pre-created on the game drive; storage summary and README
updated, including a fallback note to repoint Settings -> Directory if
RetroArch ever writes elsewhere.
gaming-backup: add opt-in snapshots for emulator BIOS (bios/) and the
RetroArch shaders/overlays dirs (cores excluded — re-downloadable). New
BACKUP_BIOS and BACKUP_RA_SHADERS flags wired through the prompts,
backup.conf, summary, and the worker script.
