[🔗](https://github.com/nyo16/nous/blob/v0.17.1/lib/nous/stream_normalizer/anthropic.ex#L1)

Stream normalizer for Anthropic API.

Handles Anthropic's SSE streaming format where events arrive as JSON maps
with a `"type"` field indicating the event kind.

## Streaming Event Types

| Anthropic Event | Normalized Output |
|----------------|-------------------|
| `content_block_delta` + `text_delta` | `{:text_delta, text}` |
| `content_block_delta` + `thinking_delta` | `{:thinking_delta, text}` |
| `content_block_delta` + `input_json_delta` | `{:tool_call_delta, json}` |
| `content_block_start` + `tool_use` | `{:tool_call_delta, %{"id" => ..., "name" => ...}}` |
| `message_delta` with `stop_reason` | `{:finish, reason}` |
| `message_start`, `content_block_stop`, `message_stop` | `{:unknown, ...}` |
| `{:stream_done, reason}` | `{:finish, reason}` |
| Error with `"type" => "error"` | `{:error, message}` |
