- Add engine-guard-stub test modules for hermes, openclaw, and paperclip runtime plugins to fail fast on unmocked @fusion/engine imports
- Update each plugin Vitest config to alias @fusion/engine to the local guard stub during test runs
- Keep setup-engine-guard behavior while removing dependency on built engine dist artifacts for plugin-local tests
- Render a compact token usage indicator in TaskCard footer with accessible labeling and token-aware styling
- Track token usage fields in the TaskCard memo comparator and expose a comparator test helper for regression coverage
- Add TaskCard tests for token usage rendering behavior and comparator invalidation on token usage updates
- Configure runtime plugin Vitest setups with an @fusion/engine source alias for reliable workspace test resolution
- Keep restart integration child_process spawn mocking aligned with execSync-driven merge verification behavior
- Add fusion-plugin-openclaw-runtime workspace package with manifest, runtime metadata, and deferred placeholder factory
- Add unit tests for OpenClaw plugin behavior and PluginRunner runtime discovery compatibility
- Document OpenClaw runtime installation and runtimeHint usage in README, getting-started, and settings reference docs
- Include built dist artifacts for the new plugin and update workspace/lockfile entries
