Crawl4AI changed API

[castelao]

We depend on ELM which depends on Crawl4AI. Crawl4AI-0.8.5 changed its API breaking compatibility. Let's hold on <0.8.5 until ELM is updated.

This PR will fix the recent failures in our Github-actions only for tox tasks since everything else relies on pixi thus have a well defined environment. Which is a real world argument for the recent discussions on keep using tox here.

Pull request overview

Pins crawl4ai to avoid the breaking API changes introduced in crawl4ai==0.8.5, maintaining compatibility with the current nlr-elm dependency chain.

Changes:

• Add a direct crawl4ai version constraint (<0.8.5) to the project’s runtime dependencies.
• Regenerate/update pixi.lock so the resolved environment reflects the new constraint.
