chore(content): add check:library-content audit for content posts (#8526)

* chore(content): add check:library-content audit for blog, library, and customer posts

Validates frontmatter against the strict ContentFrontmatterSchema, slug/folder parity, local ogImage existence, MDX compilation with remark-gfm, FAQ placement, and internal post links (including retired and moved slugs). Moves the library slug redirect maps into lib/library/retired-slugs.ts so next.config.ts and the audit share one source. Fixes two FAQ answers that rendered Markdown links as literal text.

* fix(content): tighten check:library-content link, author, and ogImage rules

Treat draft blog/library posts and customer stories missing from CUSTOMER_STORIES as unserved link targets, reserve only sibling folders that define a page or route, validate author profiles with AuthorSchema, check moved blog slug destinations, and reject ogImage paths that resolve outside public.

   - q: "Do AI agents always produce more accurate answers than chatbots?"
-    a: "Answer accuracy is the degree to which a system's response is correct and supported by the available evidence. In [Sim](https://www.sim.ai), you can inspect each workflow step and control which instructions, data, and tools the model uses. This visibility helps you find the source of an error and improve the workflow without assuming that an agent is inherently more accurate than a chatbot."

   - q: "Can a chatbot and an AI agent work together?"
-    a: "A hybrid application uses a chatbot for conversation and an AI agent for actions that require tools or multiple steps. Sim connects our [Chat interface](https://docs.sim.ai/execution/chat) to agent workflows you build in a visual workspace with connected integrations. You can give users one conversational interface while the agent handles work across connected applications."

   - q: "Do I need to know how to code to build an AI agent?"
     a: "A visual agent builder represents workflow logic as configurable blocks that connect models to tools, so you do not have to program every step. Sim provides a visual workspace for creating and testing these workflows. You can add code when needed without building the orchestration layer from scratch."
   - q: "Can AI agents run with local models?"
