docs(library): update ai-agent-observability

[icecrasher321]

Summary

• Refreshes the library post ai-agent-observability (apps/sim/content/library/ai-agent-observability/index.mdx).
• Title unchanged.
• A replacement article was merged into the existing post.
• Requested change: MERGE this material into the existing library post at library/ai-agent-observability; never swap out or overwrite the existing article wholesale. Keep every existing FAQ question verbatim unless factually wrong, every H2 and H3, every product compared, every outbound citation, every number or price,…

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)

[Low impact] The PR appears safe to merge.

Summary

Expands the observability article with guidance on silent failures, outcome checks, alerts, and incident response.

• Teams can compare agent platforms with the same failure tests.
• Teams check workflow outcomes before customers report failures.
• Teams can spot agent failures that ordinary monitoring misses.
• Teams can turn agent failures into alerts and follow-up steps.
• The guide shows its new update date and reading time.
