fix(landing): address PR #487 review feedback

- Preserve canonical camelCase platform aliases (macArm, macIntel) in the
  /download/[platform] redirect so those URLs don't lose their platform param.
- Add accessible title + role="img" to the inline Windows SVG so it passes
  Biome's a11y rule and announces to screen readers.
- On /api/releases fetch failure, show an explicit error state with a single
  intentional link to GitHub releases — no more silent GitHub fallback or
  disabled-button UX lie. Keeps normies off GitHub unless they opt in.
