Improve versioning reporting

[kunitoki]

This pull request introduces several improvements and bug fixes to class filtering and manifest compatibility reporting, along with additional test coverage. The most significant changes include ensuring that suppressed outer classes also suppress their inner classes, more granular compatibility checks for transformations and class relationships, and corresponding updates to tests.

Filtering and Manifest Generation

• Added recursive suppression of inner classes: When an outer class is filtered out (via blacklist, whitelist, internal, or source exclusion), all its inner classes are now also marked as suppressed, preventing them from leaking into the manifest or transformations. (src/tsujikiri/filters.py, tests/test_filters/test_filters.py) [1] [2]
• Updated manifest canonicalization: The manifest generation now only includes bases and inner classes that are not suppressed, and sorts them for consistency. (src/tsujikiri/manifest.py)

Compatibility Checking

• Improved class member comparison: The compatibility checker now compares base classes and inner classes, reporting added or removed bases/inner classes as additive or breaking changes, respectively. (src/tsujikiri/manifest.py)
• Granular transformation comparison: Instead of treating any transformation metadata change as breaking, the checker now compares code injections, class/function/enum transformations, and exception registrations individually, reporting only the specific changes. (src/tsujikiri/manifest.py, tests/test_manifest/test_manifest.py) [1] [2] [3]

Test Enhancements

• Added comprehensive tests for recursive class filtering and for additive/breaking changes in transformations, base classes, and inner classes. (tests/test_filters/test_filters.py, tests/test_manifest/test_manifest.py) [1] [2]

Other minor changes include a version bump to 0.23.0 and small documentation and import tweaks. [1] [2] [3] [4] [5] [6]
