docs(COOKBOOK): add scan --broken-refs and LENS visualize recipes

Summary

This PR adds documentation recipes for the LENS visualization functionality and verifies the existing scan --broken-refs documentation is complete. Specifically:

• Adds a new Recipe 6 for interactive graph visualization using the LENS subsystem (both Python API and CLI equivalents)
• Verifies that Recipe 5 already contains the scan --broken-refs documentation as requested
• Adds a cross-reference to the LENS section in ARCHITECTURE.md within the new visualization recipe

Fixes #93

Changes

• Added Recipe 6: "Interactive graph visualization (LENS)" with:
  • Python API example using LogseqGraph and GraphVisualizer
  • CLI equivalent: matryca-parse visualize /path/to/graph /path/to/output.html
  • Tips for installation and usage
  • Cross-link to Architecture §3.3 LENS topology section
• Shifted existing Recipe 6+ content down to maintain sequential numbering
• Verified Recipe 5 already contains scan --broken-refs CLI tip

Testing

• Verified the scan --broken-refs CLI tip exists in Recipe 5 (lines 130-131)
• Confirmed the new visualize recipe renders correctly in markdown
• Checked that all existing recipes remain intact and properly numbered
• Validated the cross-link to ARCHITECTURE.md points to the correct section

Thanks for the contribution — the LENS recipe is useful, and the CLI command and architecture link look good.

Before we can merge, could you please make these small updates?

1. Update the branch against current main and keep only one LENS recipe and one contributor-test recipe. The current patch duplicates the contributor section, leaves two Recipe 6 headings, and restores the old “378 tests” count; please keep the current “current suite” wording.
2. Import Path and pass Path("/path/to/visualization.html") to export_html; the current string argument raises AttributeError.
3. Remove the trailing whitespace, say that the command writes the HTML file (it does not open the browser automatically), and explicitly note that [viz] is required while [ai] is not.

Once those small updates are in, I’ll be happy to review it again.

Hi @Dodothereal, thanks for the useful LENS recipe.

Please rebase on current main and update the patch before I can merge:

• keep only one LENS recipe and the existing contributor-test section; do not restore the old test count;
• import Path and pass a Path to export_html;
• say that the command writes the HTML file, not that it opens a browser;
• remove trailing whitespace and make the [viz] requirement explicit ([ai] is not needed).

Please also avoid the unqualified “10k+ nodes” performance claim unless it has a reproducible source. Run make all after the rebase and I’ll re-review. Thanks!
