dora-studio: Web GUI for Dataflow Management in Dora

This project proposes dora-studio, a lightweight web-based GUI for viewing, editing, running, and monitoring Dora dataflows. Dora currently relies on CLI workflows, which can be less intuitive for onboarding, debugging, and demonstrations. The project will introduce a Rust-based control API to manage dataflows (list, start, stop, inspect) and a Vue-based frontend that provides a dashboard, a simple visual editor, and a live monitoring interface. The goal is to complete the full workflow loop: inspect, edit, run, and observe dataflows in a unified interface. Expected deliverables include the control API, a functional web UI for managing dataflows, a basic graph-based editor, live status monitoring, and documentation.
