Ed Zynda 996b15c9b9 fix(extensions): return nil error for blocked/disabled tools so LLM sees the reason
Tool blocking via OnToolCall and SetActiveTools returned both a
ToolResponse (IsError=true) and a Go error. Fantasy treats a non-nil
Go error from tool.Run() as a critical failure, aborting the agent
loop without delivering the tool result to the LLM. The model never
saw the block reason and would retry or hallucinate.

- Return nil error for blocked tools (OnToolCall Block=true)
- Return nil error for disabled tools (SetActiveTools)
- Return nil error for extension tool execution failures
- Update tests to assert nil error (IsError response conveys the error)

Fixes #20
