v0.3 Phase 4c: HC toggle + texture-intensity slider + grain overlay

Browse Source 
Three additions land together so the slider is meaningful from day
one (instead of recording a preference that nothing consumes yet).

Static grain overlay.

  - src/design-system/v0.3-quietware-tokens.css adds a fixed-position
    body::after element that ships an SVG feTurbulence noise tile
    repeated across the viewport. Opacity reads from
    --quietware-texture-opacity. mix-blend-mode: overlay produces the
    soft notebook-paper feel without obscuring content.
  - pointer-events: none so clicks pass through. Active only under
    html[data-design="quietware"]. High-contrast forces opacity to 0
    via the existing HC palette block.

QuietwareAccessibilityControls component.

  - NEW: src/lib/components/QuietwareAccessibilityControls.svelte.
    Two controls, both quietware-only:
      1. High-contrast toggle wires html[data-contrast="high"].
         Overrides the OS prefers-contrast: more query when explicitly
         on. Built on LumotiaToggle so it inherits the accessible
         label + description pattern.
      2. Texture-intensity slider, range 0.05 to 0.08, step 0.005,
         default 0.06. Sets --quietware-texture-opacity inline on
         <html>, overriding the per-mode default in the tokens CSS.
         Disabled while high-contrast is on. Reset button restores
         0.06.
  - Persistence: localStorage keys
      lumotia:quietware:high-contrast
      lumotia:quietware:texture-opacity
    so choices survive dev rebuilds and full restarts. Full
    integration with the central Preferences store is a follow-up;
    localStorage keeps Phase 4c contained.

SettingsPage Accessibility section.

  - Imports the new QuietwareAccessibilityControls component.
  - Renders {#if isQuietware} <QuietwareAccessibilityControls />
    {/if} immediately after the existing AccessibilityControls block.
  - Search filter copy extended to cover the new control vocabulary.

Verified.

  - npm run check: 0 errors, 0 warnings across 5706 files.
