- Introduced async demo functionality in the README, allowing for asynchronous data preparation before rendering components.
- Updated WccDashboard, WccProperties, and WccSidebar to support Promise-based template factories.
- Implemented resolveTemplateFactory to handle both synchronous and asynchronous template results.
- Added tests for resolveTemplateFactory to ensure correct behavior for both sync and async templates.
- Updated pnpm workspace configuration.
