- Fixed OAuth client configuration to properly use localhost for client_id and 127.0.0.1 for redirect_uris per RFC 8252 and ATproto spec - Added proper grapheme counting using RichText API instead of character length - Fixed thread splitting to account for link suffix and thread indicators in grapheme limits - Added GOOGLE_EMBEDDING_DIMENSIONS env var to all env files - Added clear-nodes.ts utility script for database management - Added galaxy node detail page route 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
