Why: Dev's combination check requires nested library pins to match the Dev
top-level pointers; Dev moves agent-native to 3b92cb6 (reasoning capture and
replay, Agent-Native #41) for the quality P2-I2 work.
Evidence: SELF - 3b92cb6 is an ancestor of Agent-Native main (merge of #41);
go build/test in the Dev worktree runs after this bump (recorded on the
phase02 task card).
Impact: Pin only; squad does not consume the thinking fields.
