- install.sh: API key prompt now asks for DEEPSEEK_API_KEY

-For a guided setup, run the installer:
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/AgenticMatrix/Coder-Agent/main/install.sh | bash
-```
+> **Note:** The installer defaults to **DeepSeek** as the LLM provider. To use Anthropic or OpenAI, set the corresponding API key and edit `~/.coder/settings.json`.
