ssr mackup scan now only suggests NEW files — it never overwrites an
existing ssr-*.cfg. Once created, the file belongs to the user who
edits it directly in ~/.mackup/ to customise which paths are backed up.
- _ssr_mackup_write_cfg: returns early if file already exists
- scan: drops UPD logic; only shows NEW suggestions
- _ssr_mackup_resolve_paths: removed SSR_MACKUP_SELECTIVE_PATHS support
(ssr.conf config variable removed — edit the cfg files instead)
- Scan output: hints to edit files directly after creation
