Add Ollama and LiteLLM backend support (v0.2.0)

Add two new auth modes for projects alongside Anthropic and Bedrock:
- Ollama: connect to local or remote Ollama servers via ANTHROPIC_BASE_URL
- LiteLLM: connect through a LiteLLM proxy gateway to 100+ model providers

Both modes inject ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN env vars into
the container, with optional model override via ANTHROPIC_MODEL. LiteLLM
API keys are stored securely in the OS keychain. Config changes trigger
automatic container recreation via fingerprinting.
