LLMAdapter Constitutional Implementation — thin sovereignty across one Product.ai backend surface

Define and ship the `LLMAdapter` interface as Product.ai's constitutional pattern for talking to model providers. One internal interface across all production code on the chosen surface. Pinned model versions explicitly. Reasoning effort set explicitly. System prompts in repo. No vendor SDK imports in business logic. The candidate picks one Product.ai backend surface and migrates it end-to-end. Real production code, real provider switch validation.
