Remove redundant timeout field, mention it in prose instead

The default timeout for prompt hooks is already 30s. Move the
timeout documentation to the prose note rather than cluttering
the example JSON with a no-op field.

 This uses `type: "prompt"` instead of `type: "command"` -- Claude Code sends the hook's prompt plus the assistant's response to a fast model (Haiku), which returns a yes/no judgment. If rejected, the `reason` is fed back to Claude as its next instruction, forcing it to continue.
 
-**Important:** The prompt must explicitly instruct the evaluator to respond with raw JSON only. Without this, Haiku wraps the JSON in markdown code fences or adds explanatory text, which fails JSON parsing and silently breaks the hook.

Prompt hooks default to a 30-second timeout; adjust with the `timeout` field if needed.
