[BUG] Claude needs to recognize "prefix commands" like `timeout`

When Claude asks for confirmation for a command, it bases whether it needs to ask for confirmation or not on the first keyword in the command. However, for some commandline tools (in particular timeout and also time, but another example that Claude is not likely to run is nohup), Claude asks permission to run timeout commands, when it really should be asking permission to run the command right after the timeout keyword.
