Simplify mutation: override providers instead of mutating endpoints

- mutate=true now overrides anthropic/openai provider configs to route through cli_proxy_api
- Use set_provider! from OpenRouter 1.2 for intentional overwrites
- Removed endpoint mutation logic (provider transform handles model names)
- Bump version to 0.2.0, require OpenRouter 1.2
