docs(library): update openai-vs-n8n-vs-sim

[icecrasher321]

Content update to apps/sim/content/library/openai-vs-n8n-vs-sim: Refresh the existing blog post in place at /blog/openai-vs-n8n-vs-sim; do not create a new URL or redirect. Replace the body with the supplied answer-first comparison while retaining any existing author/date metadata and valuable original citations that still support current claims. Preserve existing facts or figures only after rechecking them against first-party sources; remove stale pricing, plan limits, integration counts, or unsupported superlatives. Keep the title shown unless the repository’s existing title differs materially, in which case retain the existing title while adding “OpenAI AgentKit” to the SEO title or introductory copy. Ensure the license distinction remains exact: Sim is Apache 2.0 open source, while n8n’s Sustainable Use License is source-available and not OSI-approved. Convert every FAQ pair into the renderer’s FAQ frontmatter without Markdown formatting or links in FAQ questions or answers. Keep the head-term route to /library/best-ai-agent-builder-2026 so this comparison does not compete with the canonical category page. Before publishing, validate the OpenAI documentation URL and every September 2026 time-sensitive statement against the linked vendor-owned pages.

The PR should not merge until the existing article author attribution is restored.

1.  Author Attribution Was Reassigned ▶

Summary

This PR rewrites the existing Sim, n8n, and OpenAI AgentKit comparison with an answer-first structure, updated licensing and deployment distinctions, current OpenAI migration guidance, expanded FAQ metadata, and a link to the canonical broader agent-builder guide.

• Keeps the existing article slug and canonical URL.
• Distinguishes Sim's Apache 2.0 license from n8n's source-available Sustainable Use License.
• Reframes AgentKit around OpenAI's current APIs, SDKs, and managed services.
• Incorrectly changes the article's existing author attribution.
