- Add canonical working-directory resolution with node mapping support in core and engine paths
- Update runtime/multi-project documentation and include published-package changesets for the merged work
- Migrate roadmap dashboard surface to the bundled plugin registry flow and adjust lazy-view integration/tests
- Default non-ephemeral agents to active state and extend related agent/route/executor test coverage
