feat(miniapp): conductor status bubble and user-waiting state

- Conductor is now permanent (alive=true always); GC transitions to
  user_waiting state instead of hiding the character
- Status emoji floats above conductor head: 🤔 thinking, ⌨ toolcall, ⏳ user_waiting
- user_waiting renders with a subtle lavender glow (rgba 167,139,250)
- _orchSetState accepts optional tool param; agent_state events now pass ev.tool
- Secretary remains plan-mode-dependent (alive=false on GC)
