docs(library): update byok-multi-model-ai-agent-builder

[waleedlatif1]

Summary

• Refreshes the library post byok-multi-model-ai-agent-builder (apps/sim/content/library/byok-multi-model-ai-agent-builder/index.mdx).
• Title unchanged.
• A replacement article was merged into the existing post.
• Requested change: MERGE this refresh into library/byok-multi-model-ai-agent-builder; do not swap or wholesale-replace the existing post. Keep the existing title unless staging already contains a demonstrably incorrect variant. Preserve every existing FAQ question verbatim unless factually wrong, every H2 and H3, ever…

Generated by the Library Post PR Updater workflow. Not built or tested locally. After the PR opens, the workflow content gate checks changed paths, frontmatter keys, FAQ placement, and internal links; CI check:library-content validates the post once it is enabled.

• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
