feat: seed network with skills, caps, and explore improvements
Publish 4 skills (using-vit, semantic-commits, bun-project, atproto-records)
and 8 caps to bootstrap explore.v-it.org with real content.
- Add dogfooding section to CLAUDE.md with shipping instructions
- Create 3 seed skills under skills/ with genuine agent-useful content
- Ship all 4 skills and 8 feature/fix caps to ATProto
- Add starter follow suggestion (jeremie.com) to getting started page
- Improve explore app: pulse indicator, AT URI record links, recent
activity in stats view, better empty state copy with getting-started links
- Fix putRecord validate flag: custom org.v-it.* collections need
validate: false since the ATProto SDK doesn't have these lexicons
