the authoritative LangChain ``tool_call.id`` (parity_v2
path: when the provider streams ``tool_call_chunks`` we
register the ``index`` and reuse the lc-id as the card
id so live ``tool-input-delta`` events can be routed
without a downstream join). Either way, the same id is
preserved across ``tool-input-start`` / ``-delta`` /
``-available`` / ``tool-output-available`` for one call.
