Crate gate4agent 

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

Three transport modes:

• Pipe mode: NDJSON-streaming pipe sessions (Claude, Codex, Gemini, OpenCode)
• PTY mirror: spawns agent in real PTY, captures raw output, vt100 parsing
• ACP mode: bidirectional JSON-RPC 2.0 over stdio (Gemini, OpenCode, Claude ACP adapter)

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

Entry points

• TransportSession — thin dispatch router: pipe or PTY
• PipeSession — direct pipe session entry point (restored for 0.1.x compatibility)
• pty::PtySession::spawn — PTY mirror mode (unchanged)
• AcpSession — ACP transport (multi-turn JSON-RPC 2.0, Gemini/OpenCode/Claude)
• MultiCliManager — high-level session manager for the chart app
