  //   merged with defaults. Called fresh on every read so the plugin always
  //   sees the live shell.json entry, not a stale snapshot from when create()
  //   was first called.
  // hostBridge: object with these methods (all optional):
  //   - persistSettings(pluginId, settings): write back to shell.json via
  //     the shell's updateEntryInline helper.
  //   - openPanel(pluginId, screen, buttonItem): summon the plugin's panel
  //     entry point through the shell's plugin host.
  //   - closePanel(pluginId, screen): hide a previously-summoned panel.
  //   - currentScreen(): return the screen the plugin should anchor to.
  // togglePanel is provided by the factory itself and routes through the
  // open/closePanel bridge methods. Main.qml service instances are wired
  // separately by the shell and set on api.mainInstance once instantiated.
