🛡️ Shield: Specific exception assertion in parse_filter_args test

[fderuiter]

🛑 Vulnerability: The tests for parse_filter_args were catching the generic Exception base class. This creates a "silent failure" test anti-pattern, where the test could pass for an entirely incorrect reason (like a syntax error or a typo within the test body), masking real bugs.
🛡️ Defense: Modified tests/unit/cli/test_parse_filters.py to specifically catch typer.Exit and strictly assert that the exit_code equals 1.
🔬 Verification: You can run this test in isolation with poetry run pytest tests/unit/cli/test_parse_filters.py. I also performed a mutation test by temporarily returning code=2 in the source file, which caused the test to successfully fail.
📊 Impact: Increases test suite reliability and confidence by ensuring the application fails exactly how and where it is expected to fail.
