// `support.summarize` — EXECUTOR (server-only).
//
// Calls `@voltro/ai`'s `generateObject`, which constrains the model
// output to the `SummaryResult` Effect Schema (converted to JSON Schema
// for the provider, then decoded back so brands/refinements hold). A
// provider failure or malformed output surfaces as a typed `AiError`
// (`reason: 'generation' | 'decode'`) on the Effect failure channel —
// declare it on the descriptor's `error:` to surface it typed to the
// client, or `Effect.catchTag('AiError', …)` to handle it here.
//
// The provider is read from env (AI_PROVIDER / AI_MODEL + the key var)
// because we don't pass `provider`. No key → the call fails with an
// `AiError`; the app still BOOTS and discovers this action regardless.
