fix(cli): skip transform when table missing after header-only CSV (fixes #702)

Browse source 
insert_upsert_implementation and memory multi-file import call
Table.transform() after TypeTracker runs. For a CSV with only a header row,
insert_all yields no rows and may not create the table; transform() then
asserted. Only run transform when the table exists.

Covers both the insert command path and the memory command path.
