docs: consolidate and update all documentation for launch readiness

- Rewrite root README.md with proper project overview, tech stack, and repo structure
- Remove duplicate CLAUDE.md files (root, onchain, ponder) — AGENTS.md is the standard
- Update HARBERG.md to reflect Stage 1 completion and Stage 2 evolution
- Delete stale onchain/testing_todos.md (all high-priority items completed)
- Update VERSION_VALIDATION.md for VERSION=2
- Trim root AGENTS.md: replace Docker duplication with docs/docker.md reference
- Trim onchain/AGENTS.md (129→71 lines): reference TECHNICAL_APPENDIX for formulas
- Trim web-app/AGENTS.md (278→55 lines): remove internal API docs, keep architecture
- Rewrite onchain/README.md: add contract table, deployment addresses, analysis links
- Trim services/ponder/README.md: remove stale subgraph comparison
- Add otterscan to docs/docker.md service topology
- Update TECHNICAL_APPENDIX.md references

Net: -388 lines across documentation.

-## Comparison with Subgraph
-
-| Feature | Subgraph | Ponder |
-|---------|----------|---------|
-| Sync Speed | 1x | 10-15x faster |
-| Hot Reload | ❌ | ✅ |
-| Language | AssemblyScript | TypeScript |
-| Setup | Complex (PostgreSQL, IPFS, Graph Node) | Simple (Node.js) |
-| NPM Packages | ❌ | ✅ |
-| Type Safety | Requires codegen | Automatic |
-
-## Deployment Options
-
-### Railway (Recommended)
-```bash
-npm run build
-# Deploy to Railway with DATABASE_URL configured
-```
+## Deployment
 
 ### Self-Hosted
 ```bash
-DATABASE_URL=postgresql://... npm run start
+DATABASE_URL=postgresql://... PONDER_NETWORK=BASE npm run start
 ```
 
-### Docker
-```dockerfile
-FROM node:20-alpine
-WORKDIR /app
-COPY package*.json ./
-RUN npm ci --only=production
-COPY . .
-ENV PONDER_NETWORK=BASE
-CMD ["npm", "run", "start"]
-```
-
-## Troubleshooting
-
-### Issue: "No chain configured"
-**Solution**: Ensure `PONDER_NETWORK` is set correctly in `.env`
-
-### Issue: Slow initial sync
-**Solution**: Provide a faster RPC URL via environment variables
-
-### Issue: Database errors
-**Solution**: For production, use PostgreSQL instead of SQLite:
-```bash
-DATABASE_URL=postgresql://user:pass@host:5432/db npm run start
-```
-
-## Migration from Subgraph
-
-This Ponder implementation maintains complete parity with the original subgraph:
-- Same entity structure (Stats, Positions)
-- Identical ring buffer logic
-- Same tax rate mappings
-- Compatible GraphQL queries
-
-Key improvements:
-- 10-15x faster indexing
-- No Docker/Graph Node required
-- Hot reload for development
-- Direct SQL access for complex queries
-- Full Node.js ecosystem access
+### Troubleshooting
+- **"No chain configured"**: Ensure `PONDER_NETWORK` is set in `.env`
+- **Slow initial sync**: Provide a faster RPC URL
+- **Database errors**: Use PostgreSQL for production (`DATABASE_URL` env var)
