fix(theseus/updater): --updated flag so silent install actually reinstalls

Browse source 
Users reported Theseus being uninstalled by the auto-updater and never
coming back. Reproduced on 0.3.31:

The 'Install & restart' handler was spawning the NSIS setup with
just [\"/S\"]. Our config is oneClick:false + perMachine:false +
allowToChangeInstallationDirectory:true, so NSIS in silent mode:

  1. runs the old uninstaller (wipes install dir + registry path)
  2. hits the install phase, which in wizard mode expects UI to pick
     the install directory
  3. silent mode has no UI, registry path is gone → exits without
     installing anything

Result: browser gone, nothing left, no error surfaced to the user.

Fix: pass --updated alongside /S. electron-builder's NSIS template
treats --updated as 'this is an auto-update, reuse the existing
install directory from registry, don't rerun the uninstaller'.
--force-run relaunches the app after install.

Users stuck on 0.3.31 need to manually install 0.3.32 once (from
dl.silentmode.st) — the auto-updater in 0.3.31 will not recover on
its own. Their %APPDATA%\theseus-navigator profile is untouched by
the uninstall so vault, addons and settings survive the reinstall.
