docs: Document OpenRouter HTTP-Referer and X-Title headers

[continue]

Summary

Features were merged in PR #11857 and PR #11991 that add HTTP-Referer, X-OpenRouter-Title, and X-OpenRouter-Categories headers to OpenRouter API requests. These headers:

• Identify Continue in OpenRouter's activity dashboard and App Showcase
• User-configured headers in requestOptions.headers take precedence over the defaults

Documentation Needed

The OpenRouter documentation at /customize/model-providers/top-level/openrouter.mdx should be updated to mention:

• That Continue automatically sends identification headers to OpenRouter
• What headers are sent (HTTP-Referer, X-OpenRouter-Title, X-OpenRouter-Categories)
• That users can override these headers via requestOptions.headers if needed
• Link to OpenRouter's docs about these headers: https://openrouter.ai/docs/api-reference/overview#headers
