Fix failing tests: correct flag usage and test expectations

- Remove duplicate #[ignore] attribute in test_performance_regression
- Fix test_mixed_identity_chaining: use -Y (scaffold identity filter) instead of -i (mapping identity filter)
- Fix all tests using --output flag: change to --output-file
- Fix tests using -o for overlap threshold: change to --overlap (since -o is alias for --output-file)
- Fix test_scaffold_aligned_mass_filtering: adjust expectation to match span-based filtering (not aligned mass)
- Fix scaffold plane sweep tests: add -d 0 to disable rescue phase and test scaffold filtering in isolation
