[feat]: collapse cookbook recipe pages into an accordion layout, add …

[Ishxn20]

This PR restructures the cookbook recipe pages to reduce excessive scrolling and adds new configuration options to the MiniMax H3 recipe builder.

Layout changes (all 15 cookbook family pages)

The Setup, Troubleshooting, and Evidence Status sections are converted from static, always-expanded prose into collapsible sections, with a jump-navigation bar added beneath the page header for direct access to each section. This is applied consistently across all cookbook family pages to keep the shell uniform.

New configuration options (MiniMax H3 only)

The recipe builder now exposes two additional controls where the underlying scripts support them:

• GPU count (--num-gpus), available on all CUDA recipes in the family
• VAE decode backend (--video-decode-backend, full quality vs. TAEH3 preview), available on the FastH3-related recipes

The generated command updates live to reflect the selected values. Selecting a non-default value surfaces an explicit note that the configuration has not been benchmarked, consistent with the page's existing evidence-tracking conventions.

Other

Removed an outdated "Inference first, then the full workflow" roadmap notice from the cookbook index page.

Testing

• Extended docs/generate_examples.py's cookbook validator to enforce the new knob schema, including verifying that each knob's flag is present in its associated source script (directly or via an inherited argument parser).
• Built the full documentation site locally and verified in-browser that sections expand/collapse correctly, jump-navigation links resolve to the correct anchors, and knob selections correctly update the displayed command, caveat notes, and URL query parameters across recipe and runtime switches.
• Ran python3 docs/generate_examples.py to confirm all cookbook data and generated documentation pass existing validation.
