Interactive WebSocket CLI

Interactive WebSocket CLI (iwscli) v1.5.0 is an interactive command-line tool for debugging and testing WebSocket connections. It provides an interactive client (`wscli connect`) and server (`wscli listen`), as well as a proxy tool (`wstee`) for monitoring WebSocket traffic. Key differentiators include interactive keypress-driven commands for sending messages (client) and managing multiple clients (server), pipe mode for stdin/stdout integration, support for file-based input/output, and configurable WebSocket options via JSON. Released March 2023, with a steady cadence of minor updates. Commonly used in development workflows for manually testing WebSocket endpoints or proxying traffic.
