fix(assets): remove semi-white background artifacts from logo SVG and PNGs

Stripped 8 near-white path layers (brightness > 200) from the traced SVG,
leaving only amber/gold tones. Regenerated all PNG variants from the
cleaned SVG. Validated on dark and red backgrounds with zero artifacts.

+## Brand Assets
+
+The design system ships logo assets as static files via the `./assets/*` package export. These are not React components — they resolve to file URLs when imported via a bundler. All PNGs have transparent backgrounds.

+Header has: icon and label (no chevron — the entire row is clickable). Active section gets the amber left-border accent (existing pattern). Clicking anywhere on the header row calls `onToggle`.
 
 **Implementation detail:** `Sidebar.Section` and `Sidebar.Header` need to know the parent's `collapsed` state to switch between expanded and icon-rail rendering. The `<Sidebar>` component provides `collapsed` and `onCollapseToggle` via React context (`SidebarContext`). Sub-components read from context — no prop drilling needed.
