Add regression tests for vec0_parse_vector_column edge cases

Browse source 
Add SQLITE_EMPTY tests for non-vector column inputs (primary key,
partition key, unknown types) and SQLITE_ERROR tests for zero
dimensions and empty brackets. Tighten existing error assertions
from rc != SQLITE_OK to exact expected return codes.
