/**
 * Anthropic Messages adapter. Claude Code speaks the Anthropic Messages API to
 * whatever `ANTHROPIC_BASE_URL` points at, so to back it with a local model we
 * translate `/v1/messages` (and `/v1/messages/count_tokens`, and the
 * `/v1/models` discovery probe) to and from the gateway's OpenAI Chat
 * Completions core.
 *
 * Layers:
 * - `anthropic-wire.ts` — request types
 * - `anthropic-codec.ts` — JSON request/response translation
 * - `anthropic-stream.ts` — SSE translation
 * - `anthropic-models.ts` — Claude picker and `/v1/models`
 * - this module — HTTP handlers that wire the codec to a `Backend`
