Build me an AI Assistant plugin for Acode that opens from the command palette and gives me a simple chat screen to talk to different AI models.

I want it to support OpenAI, Google, Ollama, Groq, and other OpenAI style providers, with a setup flow that asks for a passphrase, saves the API key securely, then lets me pick the provider and model. If the provider is OpenAI style, let me enter the base URL and model manually.

The chat should remember recent context so replies feel continuous, and I should be able to view chat history and switch providers or models from inside the chat. Make the replies easy to read with markdown styling and syntax highlighting.

If you need to look up current docs online for Acode or any provider details, go ahead and do that. Keep the UI clean, friendly, and usable inside the editor.
