Introduces llm.Parse(spec) backed by an extensible Registry that resolves model strings like "openai/gpt-4o", aliases like "fast", and named targets like "m5/qwen3:30b" (via LLM_M5 env var DSNs) into ready-to-use *Model objects. Extension points: RegisterProvider, RegisterAlias, RegisterResolver. Adds Foreman constructor and sentinel errors ErrAliasLoop, ErrUnknownProvider, ErrInvalidDSN.
