- 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

- pkg/neo4j/query-events_test.go: Add query builder tests
