Summary

• Resolve Gecko profiler resource names to Python module names where available.
• Distinguish resources from different packages that contain files with identical basenames.
• Preserve readable fallback names for unresolved paths and synthetic filenames.
• Add regression tests for module-name resolution and path handling.

Tests

• Gecko collector tests: 17 passed using the local test runner.
• module_utils tests: 4 passed using the local test runner.
• git diff --check: passed.
• The full CPython test suite has not been run locally because the required CPython build and extension modules are unavailable.

Issue

Related to #161299.

• Issue: Consider module names for Gecko profiler resources #161299

Why not just using os.path.sep for the separator in filenames? You don't need to have the if either. And it's not really a norm_filename as normalized filenames are not that.

I think a lot of this logic can be simplified using pathlib.Path.

Thanks for both suggestions!

I've simplified the fallback path handling using pathlib, replacing the manual string-splitting logic with Path.name and Path.parent.name. I've also removed the misleading norm_filename variable and the unnecessary conditional around separator replacement.

I retained PureWindowsPath to handle Windows-style paths correctly on POSIX systems. Backslashes are replaced with forward slashes before calling extract_module_name() to ensure module names are resolved consistently across platforms.
