I don't feel like figuring out why the VCR cassette went stale.

Note

Updates the recorded HTTP interactions to match current upstream API responses, unblocking the failing test.

• Re-records tests/cassettes/test_equations[docling].yaml with up-to-date Crossref, Semantic Scholar (still 404), and Hugging Face responses
• Refreshes response bodies/headers: new dates/ETags, content lengths, rate limit headers, user-agent (torch/2.9.1), and request IDs
• Hugging Face model metadata updated (new sha, downloads/likes, added docling_heron_400.png, updated tags)
• Interaction order adjusted (Crossref first), keeping request URIs and methods aligned with current behavior

Pull request overview

This PR refreshes the VCR cassette file for the test_equations[docling] test, which was causing test failures due to mismatched HTTP requests. The cassette records HTTP interactions with external APIs (Semantic Scholar and HuggingFace) to enable deterministic testing without making actual network calls.

Key changes:

• Updated API interaction timestamps from November 2025 to January 5, 2026
• Reordered the two Semantic Scholar API requests in the recording sequence
• Refreshed HuggingFace model metadata to reflect current state (download counts, SHA hashes, model details)
