/**
 * Adapter: wrap a custom `ApiHandler` (from the `@cline/llms` handler registry)
 * as an `AgentModel` for the agent runtime.
 *
 * The agent runtime builds models via `createAgentModelFromConfig`, which goes
 * straight to the gateway. Hosts can register provider handlers that need
 * host-only dependencies (e.g. the VS Code `vscode.lm` API) via
 * `registerHandler(providerId, factory)`. Those produce an `ApiHandler`
 * (`createMessage` -> `ApiStreamChunk`), which this adapter converts into the
 * `AgentModel` contract (`stream` -> `AgentModelEvent`).
 *
 * This is the inverse of the gateway's `toApiStreamChunk` in
 * `@cline/llms` `compat.ts`.
