fix: remove obsolete tests referencing deleted prepare-levelup.sh

- Fix catalog.json version requirement (>=0.1.0 → >=0.0.80) to match extension.yml
- Delete test_prepare_levelup.py (tests old prepare-levelup.sh script)
- Remove test_prepare_levelup_outputs_trace_file from test_trace_command.py

The old prepare-levelup.sh was replaced by setup-levelup.sh in the levelup
extension with different outputs (CDR-focused vs feature artifact paths).
