chore: upgrade biome to 2.5.1 and fix check issues

- Upgrade @biomejs/biome from 2.3.11 to 2.5.1
- Run biome migrate: update schema URL and replace deprecated
  linter.rules.recommended with preset
- Switch check script from pnpx to local biome to avoid version skew
- Add <title> to logo.svg to satisfy a11y/noSvgWithoutTitle
