Write token usage to meta from choices/usage (OpenAI/Anthropic-style).

Collects every non-empty usage dict found (top-level usage_key, response_metadata, each choices[] entry, nested message usage). By default, deduplicates identical usage snapshots before summing: same (prompt_tokens, completion_tokens, total_tokens or prompt+completion) only counts once (typical when response_usage mirrors choices[0].usage). Set dedupe_identical_usage: false to restore legacy double-counting.

将 token 使用情况从 choices/usage 写入 meta（OpenAI/Anthropic 风格）。

收集找到的每个非空 usage 字典（顶层 usage_key、response_metadata、每个 choices[] 条目、嵌套的 message usage）。默认情况下，在求和前对相同的 usage 快照进行去重：相同的 (prompt_tokens, completion_tokens, total_tokens or prompt+completion) 只计算一次（当 response_usage 与 choices[0].usage 相同时的典型情况）。设置 dedupe_identical_usage: false 以恢复旧版的双重计算行为。
