plakar-incus-backup: self-heal a silently expelled incus plugin

Browse Source 
plakar's pkg backend deletes an installed ptar when its cache
re-extraction fails (observed 2026-08-24: orphaned .incus-* temps,
final ptar unlinked, 'unsupported importer protocol'). Reinstall from
the kept ptar before backing up instead of failing the night.
