fix(plugins): satisfy shellcheck + harden agent-deck backend per review

- silence SC1091 on the runtime source line (CI runs plain shellcheck without -x)
- agentdeck-window.sh: do not install an EXIT trap from a sourced file (it would
  clobber the caller's cleanup trap); clean up explicitly at each exit path and
  only ever return (pre-trap) or exit
- bound the wait on the review window still existing and fail loudly if
  'tmux new-window' fails, instead of busy-waiting forever on a sentinel that
  will never appear
