Description
Fixes the vf-tui viewer to properly handle tool_calls when they are stored as JSON strings instead of dictionary objects. This issue was preventing vf-tui from displaying tool calls for certain environments that serialize tool_calls as JSON strings in their output. I encountered this issue when testing viewing results on the ARC-AGI 1 + 2 with tool calling environment, more info about runs at my env PR
