Code Review

This pull request updates the test-harness subproject, introduces partial version support in SemVer parsing by padding with zeros, and changes the return value of string comparisons for non-string inputs from False to None. The review feedback identifies a bug in the version padding logic that breaks versions with suffixes, notes that existing tests need updates to reflect the new return types, and suggests maintaining backward compatibility for the renamed parse_version function.

[gemini-code-assist]

Renaming parse_version to normalize_version is a breaking change for consumers of this module. Given that this file is explicitly intended for backward compatibility (as noted in the header comment), it should continue to export parse_version as an alias.

Suggested change

	normalize_version,
	normalize_version,
	normalize_version as parse_version,

Not sure about this one, is this necessary? I changed it locally but the pre-commit hook reverted it :D

i think it is is ok. this is an internal function, I don't think anyone relied on it. just to be a bit more carful let's add it as a change in the description.

So you mean that we can keep it as it is right now? Sorry, I'm not entirely sure from your answer.
