sync: Workflows P2 features from private repo

- 5 bundled workflows (prep, research, connect, integrate, survey)
- quickLink tool for fast edge creation
- queryDimensionNodes tool for dimension queries
- Workflow orchestration tools (list, get, edit)
- Dimension awareness with active dimension tracking
- Unified Workflows tab in Agent Panel
- MCP server updates for workflow execution
