System reminder: toolsearch deferred

v2.1.270, what moved

SDK-CLI Agent SDK, print mode. No change to the system prompt since v2.1.269.

This is the system reminder: toolsearch deferred request, captured on its own. Its system array, its tools and every count below are this request's, not the ordinary one's. The injected-prompt ledger lists every surface the rig reaches.
