Gives the provider-operation agent-loop fixture enough time on slower build hosts while retaining an explicit test timeout.
Adds the experimental asynchronous multi-turn agent loop, ordered lifecycle events, tool scheduling, queues, cancellation, and policy generics.
Adds append-only session entries, projected provider context, semantic compaction, typed skip and failure outcomes, threshold compaction, and one provider-input recovery attempt selected by an open S7 generic.
