Bug: Owner records with more than three fields are discarded

Problem: _parse_list_owner rejects any owner list whose length exceeds 3. Google may append extra metadata (e.g., a verification flag) to owner payloads, which would cause the owner, collaborators, and added_by fields to disappear.

Evidence:

def _parse_list_owner(node: JSONValue | None) -> ListOwner | None:
    if not isinstance(node, list) or len(node) < 1 or len(node) > 3:
        return None

Suggested fix:

1. Accept len(node) >= 1, read only indices 0–2, and ignore any extra fields.
2. Add a test fixture with a 4-element owner record.
3. Verify that extra fields do not change the parsed owner.

Difficulty: good first issue
Impact: Low-Medium — prevents silent data loss when Google adds owner metadata.
