refactor(settings): a pull-out drawer, with Zoom as a category — and the menu moves to the wordmark

Creator directive, 2026-11-01. Settings stopped being a centred modal.

- **Drawer** (Controls/SettingsDrawer): hosted in PreviewPane's pull-out stack, 320px, the same
  animated-width pattern as Stream Settings / YPP / Socials / TEST, opened by the gear rail tab
  on a single left click. SettingsDrawerOpen is exclusive with the other four, both directions.
  This also removes the modal's MaxHeight-700 scroll problem for good: the drawer is the height
  of the preview.
- **Categories**: headings with controls indented beneath them. Zoom now owns *Zoom view shape*
  (Circle / Phone / Tablet) and *Zoom box follows*; Recordings, Brand logo and Scene transition
  are their own categories.
- **The app menu moved to the LlamaCasty wordmark** (right-click → Report Bug / Feature Request /
  About). Left-click still opens About. The gear tab no longer carries a menu at all, so clicking
  it does exactly one thing.

OverlayHost keeps only the Bug / Feature / About panels; its brand-logo handlers and the dev-panel
injection moved with the settings block. BrandLogoPreviewTests follows the control (same assertions,
new path). Release 0 warnings; 15 tests pass across brand logo, zoom, entitlement and preview
history.
