- Convert seed-sample-nodes into a test-only helper and remove direct execution against the real central database
- Replace private-looking host examples with RFC 5737 test-net addresses in node connection docs and ConnectNodeModal expectations
- Add Vitest aliases for @fusion/core and @fusion/engine to stabilize cross-package test imports
- Load AgentReflectionService via local engine source path in in-process runtime to avoid alias resolution failures
- Add a new NodeConnection utility that validates inputs, tests /api/health endpoints, normalizes URLs, and classifies connection failures
- Add CentralCore methods to test node connectivity and connect/register remote nodes, with duplicate-name checks and node:connection:test event emission
- Export NodeConnection types and APIs from @fusion/core for external consumers
- Add comprehensive unit coverage for NodeConnection and CentralCore connection flows, and increase dashboard assignment test setup timeout to reduce build/test flakiness
