Why: Integrate the exact Dev main pin while preserving trusted project context, vision routing, work-result context, and distinct migration identities.
Evidence: go vet ./...; go test ./... -count=1; go build ./...; CGO_ENABLED=0 go build ./cmd/agent-system; isolated PostgreSQL migration history tests.
Impact: Keep exec_env_layers at schema v35, move the feature migrations to v36-v46 in order, and fail closed on the old unpublished numbering.
