What
A child agent no longer inherits its parent's tool list verbatim; setup now computes the list for it, which is what decides whether a forked agent can use WebFetch.
Details
Setup returns both the tool list and a flag for whether WebFetch may be re-admitted.
When re-admission is allowed the list is recomputed using the agent's nesting depth and the set of currently active agents.
