chore: bump version to 0.1.1

README-only refresh — visual upgrade and i18n published to npm
so the registry page reflects the new banner and language options.

docs: visual upgrade — banner, Mermaid arch, i18n (ko/zh), GitHub alerts

- docs/media/waypath-banner.{svg,png} — hero banner with graph motif
- docs/media/waypath-og.{svg,png} — 1200x630 Open Graph social card
- README.md: centered banner, more badges, GitHub-flavored alerts,
  Mermaid architecture diagram, live sample output, comparison table,
  language switcher
- README.ko.md: Korean translation
- README.zh.md: Simplified Chinese translation

Visual-only change — no package surface changes.
