/**
 * Edge-safe wrapper around the Anthropic SDK's raw `MessageStream`.
 *
 * The raw stream's async iterator rejects with the SDK's own error types when
 * the underlying connection fails mid-stream (distinct from a `finalMessage()`
 * rejection, which the provider bundle already normalizes separately). This
 * wrapper catches those iteration failures and rethrows a normalized
 * {@link CruxAdapterError} so `textStream` consumers never see raw provider
 * exceptions. It forwards only the two members the provider bundle needs —
 * async iteration and `finalMessage()` — mirroring the OpenAI stream capture.
