Two unrelated lint blockers that CI surfaced once the file was in scope
of `black --check .` and `vulture` on the changed-file path:
- Reformat one if/and conditional that black wanted on a single line.
- Underscore-prefix unused parameter names on FakeProvider stub methods
(from_cli_args, get_output_options, display_compliance_table,
generate_compliance_output, FakePureContractProvider.from_cli_args)
and the throwaway **kw in a MagicMock side_effect lambda. These are
test fixtures whose method bodies don't reference those args; the
signatures must match the abstract contract on Provider, so we keep
positions/types and just rename to indicate intentional non-use.
No logic change.
- Implemented dynamic loading of external providers via entry points, allowing for greater flexibility in provider integration.
- Added functionality to discover compliance directories from entry points, enabling external compliance frameworks to be loaded seamlessly.
- Refactored check module resolution to prioritize built-in checks while falling back to entry points if necessary.
- Improved compliance framework loading to include both built-in and external sources, ensuring comprehensive compliance coverage.
- Enhanced CLI argument parsing to support external providers, improving user experience and configurability.
- Introduced extensive unit tests to validate dynamic loading, compliance discovery, and overall integration of external providers.
