Complete legacy relay infrastructure cleanup and documentation updates
- Remove duplicate legacy relay files from src/lib/nostr/ directory - Add deprecation notices to outdated architecture documentation - Update file path references in RELAY_HUB_ARCHITECTURE.md - Clean up all remaining references to removed NostrclientHub service - Finalize consolidation to single RelayHub service architecture This completes the relay infrastructure cleanup effort, removing all redundant code and updating documentation to reflect current architecture. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
