- [x] Add FilterByThreshold helper tests for query result filtering
- [x] Make handlers_test more robust for network-dependent update checks
- [x] Update package versions in UI

* Move to GORM + general cleanup

* feat(mcp): add observation relations discovery and scoring integration

- [x] Add find_related_observations MCP tool for discovering related observations by confidence
- [x] Integrate scoring calculator and recalculator into MCP server initialization
- [x] Add pattern, relation, and session stores to MCP server dependencies
- [x] Register MCP server in Claude Code settings during plugin installation
