🖥️ horizon: Infinite Canvas Terminal Board

horizon introduces a novel approach to terminal interaction. It is a GPU-accelerated terminal board that breaks away from traditional grid constraints, placing all command-line sessions onto an infinite canvas. Built with Rust and the egui framework, it focuses on cross-platform compatibility and high-performance rendering. This design direction is particularly relevant given the rise of AI agents like Claude Code and Gemini CLI. When running multiple autonomous coding agents or browser automation scripts simultaneously, traditional terminal window management quickly becomes chaotic. horizon uses spatial organization to help developers visually monitor and manage these parallel AI tasks on a single expansive board. This is not just another terminal emulator; it acts more like a visual console tailored for multi-agent workflows. The primary technical challenge here is maintaining smooth GPU rendering while efficiently parsing and displaying massive amounts of text output from concurrent terminal sessions.
