fix: bump polars to 1.43.2

[tschm]

Problem

polars==1.43.1 depends on polars-runtime-32==1.43.1, which has been yanked from PyPI. uv therefore cannot resolve the notebooks' inline PEP 723 dependencies, and all five marimo jobs fail:

× No solution found when resolving script dependencies:
╰─▶ Because polars-runtime-32==1.43.1 was yanked and polars==1.43.1 depends
    on polars-runtime-32==1.43.1, we can conclude that polars==1.43.1 cannot
    be used.

Fix

• Bump the inline script pin in Experiment1.py … Experiment5.py to polars==1.43.2
• Raise the pyproject.toml floor to polars>=1.43.2 so the yanked release is never named
• Relock (polars and polars-runtime-32 1.43.1 → 1.43.2)

Note

This is also what is currently red on #502 — that PR's five marimo jobs fail on the same resolution error. Rebasing it on main after this merges should turn it green.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
