Horizon – GPU-accelerated infinite-canvas terminal in Rust

SMRTR summary

Horizon is a GPU-accelerated terminal board that organizes terminal sessions on an infinite 2D canvas instead of traditional tabs or tiles. It features color-coded workspaces, built-in AI agent integration with Claude and Codex, git status panels, and smart URL/file detection. Sessions persist across restarts, maintaining panel positions and terminal history exactly as left.
