Fixes #20

[Copilot]

Pull request overview

This PR expands Python unit test coverage across the cppwg package and introduces automated coverage reporting/upload in CI to support Issue #20 (“Expand Testing”).

Changes:

• Add extensive unit tests for parsers, info objects, writers, CLI, and utility helpers.
• Enable pytest coverage collection (pytest-cov) and configure Coverage.py/pytest defaults via pyproject.toml.
• Upload coverage reports to Codecov from unit tests and selected example workflows (shapes/cells).

• The new class-level exclude_inherited_overrides has the same normalization issue as the module-level setting: a quoted string like "False" remains truthy and flips behavior. Normalize it with utils.convert_to_bool() while keeping None as the inherit/default value.

                        class_config = {
                            "exclude_inherited_overrides": None,
                            "name_override": "",
                            "source_file": "",
                            "source_file_path": "",

cppwg/parsers/package_info_parser.py:123

• The new module-level exclude_inherited_overrides value is read straight from YAML but never normalized like the package-level booleans. If a user quotes it (e.g. "False"), it stays a non-empty string and is treated as truthy, incorrectly enabling inherited-override exclusion. Normalize it with utils.convert_to_bool() while preserving None for the inherit/default tri-state.
