chore: remove vestigial wrangler config from vibes.diy/pkg

- Delete wrangler.toml (pointed to non-existent cf-worker/vibe-meta.ts)
- Remove unused deploy script from package.json
- vibes.diy deploys via Netlify, not Cloudflare Workers
- Cloudflare Workers are in hosting/pkg workspace (separate config)
- Likely leftover from aborted Netlify→Cloudflare migration
