fix: prevent tool name duplication in streaming accumulator (MiniMax/NVIDIA NIM)

Based on #11984 by @maxchernin.  Fixes #8259.

Some providers (MiniMax M2.7 via NVIDIA NIM) resend the full function
name in every streaming chunk instead of only the first.  The old
accumulator used += which concatenated them into 'read_fileread_file'.

Changed to simple assignment (=), matching the OpenAI Node SDK, LiteLLM,
and Vercel AI SDK patterns.  Function names are atomic identifiers
delivered complete — no provider splits them across chunks, so
concatenation was never correct semantics.
