idea: identifies Jan on openrouter

[STRRL]

Problem Statement

Jan doesn't appear on OpenRouter's Top Apps leaderboard because it's missing identification headers. OpenRouter tracks apps via optional HTTP-Referer and X-Title headers, allowing apps to gain visibility and community recognition.

Feature Idea

Add OpenRouter identification headers to API requests:

headers: {
  'Authorization': 'Bearer <API_KEY>',
  'HTTP-Referer': 'https://jan.ai',
  'X-Title': 'Jan',
  'Content-Type': 'application/json'
}

Benefits:

• Appear on OpenRouter's Top Apps ranking
• Increase discoverability
• Track Jan's usage statistics
• Gain community visibility

Simple implementation, significant marketing value. 🚀

I'll submit a simple PR later.
