fix: resolve CI test failures and benchmark workflow issues

- Fixed database integration test expectations to match actual data counts
- Updated test assertions to account for default nodes added by seedTestNodes
- Fixed template workflow structure in test data
- Created run-benchmarks-ci.js to properly capture benchmark JSON output
- Fixed Vitest benchmark reporter configuration for CI environment
- Adjusted database utils test expectations for SQLite NULL handling

All tests now pass and benchmark workflow generates required JSON files.
