feat: add V2 service publishing and username claiming APIs

- Add POST /services endpoint for publishing services with username verification
- Add DELETE /services/:serviceId endpoint for unpublishing services
- Add GET /services/:serviceFqn endpoint for service discovery
- Add POST /usernames/claim endpoint with Ed25519 signature verification
- Add POST /usernames/renew endpoint for extending username TTL
- Add GET /usernames/:username endpoint for checking username availability
- Add username expiry tracking and cleanup (365-day default TTL)
- Add service-to-offer relationship tracking
- Add signature verification for username operations
- Update storage schema for usernames and services tables
- Add comprehensive README documentation for V2 APIs
- Update version to 0.8.0
