/**
 * thinkingModeFor — the thinking mode a provider DECLARES for one model.
 *
 * Pattern: capability declaration (the `thinkingHandlerFor` /
 *          `cacheStrategyFor` twin). The adapter knows which thinking request
 *          each model on its wire takes and declares it
 *          (`LLMProvider.thinkingMode`); a wrapper forwards the field. Never
 *          derived from `provider.name`.
 * Role:    the ONE place the agent reads that declaration, so a malformed one
 *          is refused at build, by provider name, instead of meaning "no claim".
