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)

Root cause: DSM expects share paths (/dev) not volume paths (/volume1/dev).
The 408 errors were triggered by any additional field on the wrong path format.
- list_shares: use share["path"] directly (e.g. /dev), drop real_path from
additional — only volume_status remains
- list_dir: remove additional parameter entirely; table now shows name + type
(isdir is returned by default); update docstring to show share path examples
- client.py: remove diagnostic REQUEST and RAW ERROR stderr logging
- tests: update assertions to match share paths and two-column table output
