Template Logic Support for Playground

This project extends the Accord Project Template Playground by implementing an end-to-end, sandboxed logic execution pipeline to solve its inability to test interactive smart contract behaviors natively. By utilizing a secure Web Worker architecture, the platform will safely evaluate user-authored TypeScript logic and validate all states and requests against strict Concerto models directly in the browser. The core deliverables include an integrated Monaco-powered logic editor, an interactive contract runner UI for initialization and request handling, dynamic execution results visualization, and comprehensive multi-state contract templates. Together, these features transform the platform from a static authoring tool into a complete, interactive development workspace for smart legal contracts.
