dsh-improved-inline-edit: Real-Time Runtime Interruption

dsh-improved-inline-edit is a workflow plugin designed for DSH, aimed at solving the difficulty of adjusting direction while an agent is running. It leverages the official `agent.steer()` mechanism to allow users to dynamically insert a “Modify Requirements” input bar above the composer during agent execution, enabling seamless interruption and instruction injection. The plugin features zero UI interference, multi-line input support, visual alignment, and draft persistence. Users can send instructions without stopping the conversation, and the Agent will execute them at the next decision step. Installation requires a PowerShell script, and a full DSH restart is mandatory.
