feat(baam): add Folklore Clinical Variant Interpretation MCP

[vladimir-mitev]

Summary

• Add Helena Bioinformatics' Folklore Clinical Variant Interpretation MCP to the BAAM extension catalog.
• Publish the generated registry and bundled fallback entries from the same BAAM card.
• Use the immutable v1.3.3 BRXT release asset: https://github.com/helena-bioinformatics/folklore-mcp/releases/tag/folklore-biorouter-v1.3.3
• State the public, read-only variant-level boundary directly in the catalog: no patient or private case data; results require qualified professional review and are not diagnosis or treatment recommendations.
