fix(ui): wire details-island buttons and drop dead handlers

- Bind star button to ToggleStarCommand; wrap header and subtask
  done-check ellipses in buttons (ToggleDone / ToggleSubtaskDone).
- Wire AgentStrip copy-path button to clipboard handler.
- Remove dead Notes/PromptInput/ApproveMerge/ShowWorktreeModal code
  with no UI bindings.
