Why: the EXT-14 wiring made runmgr import cmdbus for the CommandSource
interface signatures, which adds a new edge backend/runmgr ->
backend/cmdbus outside the architecture baseline ratchet; the Dev
umbrella lint (lint-architecture) rejects the gitlink bump because of
it. The dependency direction was always meant to be inverted: runmgr
defines the port, the composition root adapts the bus.
Evidence: go build/vet clean; go test ./... 32/32 packages green;
grep confirms no internal/cmdbus import left in non-test runmgr files;
Dev-side lint re-run scheduled on the gitlink bump PR.
Impact: runmgr.CommandTool/CommandRequest/CommandResponse are local
view types; app.busAdapter now converts cmdbus types at the boundary
(Entrance still fixed to agent by runmgr). No behavior change; the
runmgr tests speak the view types instead of cmdbus ones.
