feat: add OpenRouter support and fix input disabling

- Add OpenRouter provider support with @openrouter/ai-sdk-provider - Fix input not disabling during 'submitted' state for fast providers - Apply disable logic to all interactive elements (textarea, buttons, handlers) - Clean up env.example by removing model examples and separator blocks - Upgrade zod to v4.1.12 for compatibility with ollama-ai-provider-v2 - Add debug logging for status changes in chat components
