Crate gate4agent 

gate4agent — Universal wrapper for CLI agents (Claude Code, Codex, Gemini).

Two transport modes:

• PTY mirror: spawns agent in real PTY, captures raw output, vt100 parsing
• Pipe mode: claude -p --output-format stream-json, plain OS pipes, NDJSON events

Both modes produce AgentEvent values on a tokio::sync::broadcast channel.
