 * already resolve through them — but the id actually sent to the provider did
 * not, so `generate({ model: "gpt4o" })` put the alias on the wire and the
 * provider 404'd. This closes that gap (#337).
 *
 * Deliberately conservative, because a wrong rewrite is worse than no rewrite:
 *
 * - An id the registry already knows is returned untouched, so a canonical id
 *   can never be displaced by an alias that happens to collide with it.
 * - An alias is only applied when the model it names belongs to the provider
 *   being constructed. Without that check, an aggregator or self-hosted
 *   deployment whose model is literally named "gpt4" would be silently
 *   rewritten to OpenAI's "gpt-4".
 * - Anything unrecognised passes through, so custom and brand-new model ids
 *   keep working exactly as before.

 * @param model - Model id or alias as the caller supplied it
 * @returns The canonical id when an alias resolved, otherwise null
