pi-chrome 0.10.2: interactive /chrome-trusted picker

- No-arg /chrome-trusted now shows ui.select picker with current mode +
  tradeoff for each option (on/off/auto/status)
- First-time on transition asks ui.confirm with banner warning
- Permission missing emits a clear ui.notify with fix instructions
- Direct args (/chrome-trusted on|off|auto|status) still work
