Clean up compiler warnings and document Ollama/LiteLLM backends

Remove unused `any_docker_mcp()` function, add `#[allow(unused_imports)]`
and `#[allow(dead_code)]` annotations to suppress false-positive warnings.
Update README.md and HOW-TO-USE.md with Ollama and LiteLLM auth backend
documentation including best-effort compatibility notices.

+## Ollama Configuration
+
+To use Claude Code with a local or remote Ollama server, switch the auth mode to **Ollama** on the project card.
+
+### Settings
+
+- **Base URL** — The URL of your Ollama server. Defaults to `http://host.docker.internal:11434`, which reaches a locally running Ollama instance from inside the container. For a remote server, use its IP or hostname (e.g., `http://192.168.1.100:11434`).
+- **Model ID** — Optional. Override the model to use (e.g., `qwen3.5:27b`).
+
+### How It Works
+
+Triple-C sets `ANTHROPIC_BASE_URL` to point Claude Code at your Ollama server instead of Anthropic's API. The `ANTHROPIC_AUTH_TOKEN` is set to `ollama` (required by Claude Code but not used for actual authentication).
+
+> **Note:** Ollama support is best-effort. Claude Code is designed for Anthropic models, so some features (tool use, extended thinking, prompt caching, etc.) may not work as expected with non-Anthropic models.
+
+---
+
+## LiteLLM Configuration
+
+To use Claude Code through a [LiteLLM](https://docs.litellm.ai/) proxy gateway, switch the auth mode to **LiteLLM** on the project card. LiteLLM supports 100+ model providers (OpenAI, Gemini, Anthropic, and more) through a single proxy.
+
+### Settings
+
+- **Base URL** — The URL of your LiteLLM proxy. Defaults to `http://host.docker.internal:4000` for a locally running proxy.
+- **API Key** — Optional. The API key for your LiteLLM proxy, if authentication is required. Stored securely in your OS keychain.
+- **Model ID** — Optional. Override the model to use.
+
+### How It Works
+
+Triple-C sets `ANTHROPIC_BASE_URL` to point Claude Code at your LiteLLM proxy. If an API key is provided, it is set as `ANTHROPIC_AUTH_TOKEN`.
+
+> **Note:** LiteLLM support is best-effort. Claude Code is designed for Anthropic models, so some features (tool use, extended thinking, prompt caching, etc.) may not work as expected when routing to non-Anthropic models through the proxy.
