Stylebot now recognises Vivaldi on install and update, not only after its side panel first fails.

• Detect Vivaldi by the vivExtData field on windows, so the Side panel choice is hidden from the start.
• Skip sidePanel.setOptions in Vivaldi, so the panel it opens on install and update is blank instead of its start page.

Review notes: Vivaldi still opens that panel (its bug). Making sidePanel optional stops it but crashes Chrome on tabs open before the grant, so it stays required.

Testing: unit, typecheck, lint, side panel and editor window e2e; checked by hand in Vivaldi.
