2. Add pathlib for easy file discovery.

It looks like you missed the second commit.

@RetiredWizard Thanks for the additional comments. I'll need to be better about testing my Claude generated code. I've fixed in a slightly different way by fixing the QSTRs.

I was planning on giving pathlib a pretty thorough workout by incorporating into the PyDOS directory system. Currently I'm using a Python workaround for the vfsFat mount point issue (can't traverse up a path to the root #8409) and was hoping that I might see a way to put the workaround in the pathlib core code. I'll probably put that on the back burner now though 😁

I'm not sure how the stem/name/suffix methods will be used but there were some minor differences in the results of paths that contained '.' or '..' elements between this version and cpython. Other than that, I gave most of the methods at least a brief test and everything seems to be working.

Dan and I chatted about this and he pointed out that pathlib could just be a Python library. In fact, micropython already has a simple version here: https://github.com/micropython/micropython-lib/blob/master/python-stdlib/pathlib/pathlib.py I'm going to take the native implementation out in favor of the Python one.

I do still want to fix the os implementation of cwd because pathlib will build on it and there are existing bugs filed for it.

I'm going to close this and split it into to PRs:

• Adding working_directory
• Fixing OS
