"""PR #3681 — fenced tool calls with inline args, and the fence-tag boundary.

Local fenced-block models (Ollama etc.) emit calls like ```list_email_accounts {}
with the args on the same line as the tag; the parser must execute those. The
relaxed tag pattern must NOT prefix-match longer fence tags: ```python3 is a
language hint, not a "python" tool call with content "3\n...".
