Root cause of DSM 408 was wrong path format (volume path vs share path),
not the additional parameter. Confirmed via test_additional.py that
json.dumps(["size","time"]) is the correct format; comma-separated string
is silently ignored by DSM.
- list_dir: restore 4-column table (Name, Type, Size, Modified)
- list_dir: use additional=json.dumps(["size","time"]) (confirmed working)
- SPEC.md: document share path requirement, additional format rules,
note SYNO.FileStation.Stat unavailability, remove comma-sep gotcha
- tests: restore size/mtime mock data and assertions
- delete test_additional.py (throwaway diagnostic script)
