Recovering Gemini tool calls described in prose

Gemini models sometimes describe an action in plain text instead of issuing a structured tool call; Donobu now detects and recovers those cases instead of stalling the run.

Some models — Gemini in particular — occasionally narrate a tool call ("I'll click the login button") instead of emitting the structured tool-call format Donobu expects. Previously this could stall a run or fail a step that the model had, in effect, already decided how to handle. Donobu now detects these verbalized tool calls and recovers the intended action, so the run continues.

This is a reliability fix specific to how certain models respond, not a new capability you need to configure — it applies automatically wherever Donobu talks to a tool-calling model.
