Fixing failing test_equations[docling] by caching Docling models before pytest

[jamesbraza]

The test_equations[docling] cassette was failing on Docling model queries. Docling model queries shouldn't be in this cassette, let's just cache it up front.

Note

Low Risk
CI-only changes plus a VCR cassette update; main risk is cache key/path mistakes causing slower or still-flaky CI rather than runtime impact.

Overview
Prevents test_equations[docling] from making unexpected HuggingFace Hub calls during CI by caching and pre-downloading Docling models before pytest runs.

The test-src workflow now restores ~/.cache/docling via actions/cache, downloads layout/tableformer models on cache miss, and sets DOCLING_ARTIFACTS_PATH for the test run. The test_equations[docling] VCR cassette is updated to remove previously recorded HuggingFace API interactions.

Pull request overview

Fixes the failing test_equations[docling] VCR cassette by ensuring Docling model artifacts are cached and downloaded before pytest, preventing HuggingFace Hub calls during cassette playback.

Changes:

• Removed HuggingFace Hub model metadata interactions from the test_equations[docling] VCR cassette.
• Added a GitHub Actions cache for Docling artifacts and a pre-download step for required models.
• Set DOCLING_ARTIFACTS_PATH for the pytest run to point at the cached models directory.
