docs: add Bifrost integration cookbook

[Swpn0neel]

Summary

• add a Bifrost integration cookbook notebook
• configure Bifrost's OpenTelemetry plugin to export GenAI traces to Langfuse
• demonstrate an OpenAI-compatible request through Bifrost
• register the notebook route and add the Bifrost icon

Validation

• validated notebook JSON and required Langfuse metadata and step markers
• validated cookbook route JSON
• node scripts/check-h1-headings.js
• git diff --check

The generated cookbook Markdown was not regenerated, following the repository guidance for integration-page contributions. The notebook keeps the standard placeholder for a trace screenshot and public example trace until a maintainer supplies or approves those assets.

Note

Low Risk
Documentation-only cookbook and route registration with no runtime or security-sensitive application code changes.

Overview
Adds a Bifrost AI gateway integration cookbook and wires it into the docs site at integrations/gateways/bifrost via cookbook/_routes.json.

The new notebook walks through Langfuse + Bifrost end-to-end: env setup and get_client() auth check, generating an OpenTelemetry otel plugin snippet that posts GenAI traces to Langfuse’s public OTEL endpoint (with LANGFUSE_OTEL_AUTH kept out of config), shell/PowerShell/Docker notes for starting Bifrost with that auth, and a sample OpenAI-compatible chat completion routed through the gateway. Step 6 shows a trace screenshot URL and states that a public example trace link is omitted because traces are project-specific.

Greptile Summary

This PR adds a notebook-backed Bifrost gateway integration, maps it to /integrations/gateways/bifrost, and supplies its integration icon.

• Configures Bifrost’s OpenTelemetry plugin to export GenAI traces to Langfuse.
• Demonstrates an OpenAI-compatible request through a locally running Bifrost instance.
• The route and catalog discovery path are correctly connected, but the reader setup instructions and example-trace link remain incomplete.

Confidence Score: 4/5

The PR appears safe to merge after non-blocking documentation cleanup, particularly completing the Bifrost startup prerequisites and removing the placeholder trace link.

The route and notebook publication flow are sound, but the walkthrough is not runnable from its stated steps without external setup knowledge and exposes an unfinished link to readers.

### Issue 1
cookbook/integration_bifrost.ipynb:206
**Placeholder trace link**

The published “Example trace in Langfuse” link uses the literal `TODO: replace with...` text as its destination. Notebook conversion preserves this value, while link validation skips destinations that are neither HTTP(S) nor root-relative. Readers will therefore receive an unusable link without CI detecting it. Replace it with an approved public trace URL or remove the link until one is available.

### Issue 2
cookbook/integration_bifrost.ipynb:152
**Missing gateway prerequisites**

The notebook tells readers to start Bifrost but provides no installation or startup command and no provider or virtual-key setup guidance. The next step assumes a gateway running on localhost with a configured model provider and valid virtual key, so readers cannot run the example from the documented steps alone. Add explicit prerequisites and startup/provider-key instructions, or link to the exact Bifrost setup procedure.
