claudetool: replace timeout parameter with slow_ok boolean

Empirically, the agent doesn't set timeouts long enough,
and doesn't retry on failure.

Give it only one decision to make: Is this maybe a slow command?

If, horror of horrors, your project can't accomplish tasks within the
default timeouts, there's a new command line flag to adjust them.
