Code Review

This pull request adds a new community-contributed Vue 3 renderer to the ecosystem documentation. My review found one issue: the documentation link for the new renderer points to a localhost address, which needs to be corrected to a public URL or removed.

Welcome contribution, @shawnwang15 — the Vue renderer looks well-built, with 20+ components and a docs site. Happy to add it to the community table.

One thing to flag: the table currently shows ✅ v0.8 | ❌ v0.9, which matches what I see in the source (processor.ts imports from @a2ui/web_core/v0_8). Your README claims v0.8/v0.9/v0.10 compatibility — could you clarify? If v0.9 support is planned but not yet implemented, the table entry is accurate as-is. If you do have v0.9 support via a different code path, please point me to it and I'll update the table.

Otherwise this looks good to merge — nice work on the docs site and npm publishing.
