phase 3: system tray icon

- KStatusNotifierItem with status indication (passive/active/attention)
- Tooltip: session count and active count
- Right-click menu: New Session, Sessions submenu (per-session kill),
  Stop All, Quit Daemon
- Live updates via D-Bus signals (SessionCreated, SessionKilled,
  StateChanged)
- Builds as ollie-tray (104KB), links KF6StatusNotifierItem + Qt6
