Tool-search deferred-tools delta now has a fast latch path avoiding full recompute

What

The internal logic that decides whether to compute and announce a deferred_tools_delta (a signal that new tools have become available partway through a session) now first tries a quick cached check using toolPoolRefreshes and aheadOfRequest. It only falls back to the previous, more expensive full set of eligibility checks if that quick check doesn't resolve the question.

Why

This is a performance change: it avoids redoing full eligibility computation on every check, which should make detecting newly available tools mid-session cheaper without changing what tools end up available.
