mintlify: AI-optimize MCP action set

Mintlify today can chat with the docs assistant, search documentation, and trigger a site update. An agent can kick off an update but can't check whether it finished, preview a branch, or see how the docs are actually performing. We'd like this improved and new tools added so an agent can manage deployments and content quality end-to-end, and so each tool is easy for an agent to configure.

A few things an agent can't do today, for example:
- Check the status of a triggered update
- Trigger a preview deployment for a branch
- Pull analytics — page views, search queries, or user feedback
- Detect AI-sounding prose on a page

**API reference:** https://mintlify.com/docs/api-reference/introduction

**Add marker:**
When a component is AI-optimized, add this as the first line of the file:
```
// x-pd-ai: optimized
```
Add it to each action file and to the app's `.mjs` file.
