docs(blog): update multiplayer

[icecrasher321]

Content update to apps/sim/content/blog/multiplayer: Refresh the existing post at https://www.sim.ai/blog/multiplayer in place and preserve the /blog/multiplayer URL. Replace the current body with the answer-first structure in article_markdown, while retaining any existing sourced technical-history facts, figures, and citations that remain accurate. Before publication, compare the current post line by line and carry forward those sourced details rather than silently deleting them; remove or update only stale product claims. Verify the live Multiplayer UI and current documentation before publishing, especially the exact mechanics for invitations, simultaneous editing, presence indicators, permissions, testing, and deployment, and do not add unverified capability claims. Keep the existing title unless repository frontmatter uses a slightly different canonical title. Preserve existing metadata that is still accurate, improve the meta description around collaborative AI agent workflow building, add the canonical internal link to /library/best-ai-agent-builder-2026, and retain the Sim and documentation calls to action. FAQ questions and answers must remain plain text downstream with no Markdown links or inline formatting. The existing source was not available in the brief, so the publishing editor must perform the explicit source-preservation check against the repository version before merging.
