sqlite3: `arraysize` doesn't reject negative values

[ever0de]

Current Problem:

cursor.arraysize = -3  # ← Should reject negative
# Current: Accepts it
# Expected: Raise ValueError

Actual Test Result:

ERROR: arraysize accepted -3, should raise ValueError

Test Code:

def test_invalid_array_size(self):
    self.assertRaises(ValueError, setattr, cursor, 'arraysize', -3)

Affected Tests (1 test):

• test_sqlite3/test_dbapi.py::CursorTests::test_invalid_array_size
