Walkthrough

This PR adds a new documentation guide for calling Tuning Engines through a governed, OpenAI-compatible endpoint from Trigger.dev tasks. The change registers a new page in the docs navigation structure and creates the MDX page with frontmatter, an explanation of the pattern, required environment variables (TE_INFERENCE_KEY, TE_MODEL), a complete TypeScript task example that sends POST requests to /v1/chat/completions with authorization and correlation headers, a test payload for the Trigger.dev dashboard, and implementation guidance covering secret storage, run ID correlation, and policy-approval-driven retries.

Thanks for the pointer. I opened a vouch request first so this can follow the project process: https://github.com/triggerdotdev/trigger.dev/issues/3712\n\nOnce vouched, I can reopen this contribution or submit a fresh PR if that is cleaner for maintainers.
