Provides a global threading.Event that any tool can check to determine
if the user has requested an interrupt. The agent's interrupt() method
sets this event, and tools poll it during long-running operations.
Usage in tools:
from tools.interrupt import is_interrupted
if is_interrupted():
return {"output": "[interrupted]", "returncode": 130}
