Say checked, healer-acted and act-recorded on their seats' subjects, where their consumers hear them, and pin mesh-sdk fbd00c8 (issues 1952, 1953)

stdio.Emit put them on the module's subject, which no consumer of a seat's event hears. The manifests no longer list a seat's events as the module's own, which the SDK now refuses. mesh-hand-acts takes its act layout and names from mesh-sdk's handacts, and counts a repeated cause by its Repair rule.
