/**
 * A provider factory such as `bedrock(options)` captures configuration in a
 * definition, while every OpenAI client receives a fresh runtime from
 * `definition.configure()`. Keeping definitions out of the provider object
 * makes providers opaque and prevents arbitrary objects from imitating one.
 * It also leaves provider-specific dependencies outside the core SDK.
 *
 * The registry lives on `globalThis` under a global symbol so a provider made
 * by one copy of the package still works with another copy, including mixed
 * CommonJS and ESM installations. The WeakMap avoids retaining discarded
 * provider configurations.
