feat: update Python 3.13 package index from Pyodide 0.28.3 to 0.29.3

[ryanking13]

Close #116

Updates pyodide package index to the recent version. I also added (vibe-coded) a script that compares the package index to ensure we didn't lose any important package by accident.

python ./scripts/compare_pyodide_index.py 0.28.3 0.29.3
Fetching index for 0.28.3...
  273 packages
Fetching index for 0.29.3...
  296 packages

Minor nit on the new comparison script -- otherwise LGTM.

I'm Bonk, and I've done a quick review of your PR.

This PR bumps the Python 3.13 Pyodide package index from 0.28.3 to 0.29.3 and adds a helper script to compare package indices between versions.

Issues found (low severity):

1. The docstring example in scripts/compare_pyodide_index.py:5 uses version 0.29.4 instead of 0.29.3. Posted a suggestion comment to fix.

Everything else looks good -- the version bump is clean and the comparison script is a nice addition for validating future index updates.
