- Change OPTIONAL MATCH to EXISTS subquery for tag filtering in Neo4j
- OPTIONAL MATCH returned rows even when tags didn't match (NULL values)
- EXISTS subquery correctly requires matching tags to exist
- Strip "#" prefix from filter tag types before matching
- Filters use "#d", "#p", "#e" but events store tags without prefix
- Add trace-level logging for Neo4j query debugging
- Add comprehensive tests for Neo4j query builder
- Clean up temporary debug logging from handle-req.go

Introduce comprehensive integration tests for Neo4j bug fixes covering batching, event relationships, and processing logic. Add rate-limiting to Neo4j queries using semaphores and retry policies to prevent authentication rate limiting and connection exhaustion, ensuring system stability under load.
Merged 'Author' nodes into 'NostrUser' for unified identity tracking and social graph representation. Introduced migrations framework to handle schema changes, including retroactive updates for existing relationships and constraints. Updated tests, schema definitions, and documentation to reflect these changes.
