helios-remote/crates/client

helios-client (Phase 2 — not yet implemented)

This crate will contain the Windows remote-control client for helios-remote.

Planned Features

• Connects to the relay server via WebSocket (wss://)
• Sends a Hello message on connect with an optional display label
• Handles incoming ServerMessage commands:
  • ScreenshotRequest → captures the primary display (Windows GDI or windows-capture) and responds with base64 PNG
  • ExecRequest → runs a shell command in a persistent cmd.exe / PowerShell session and returns stdout/stderr/exit-code
  • ClickRequest → simulates a mouse click via SendInput Win32 API
  • TypeRequest → types text via SendInput (virtual key events)
• Persistent shell session so cd C:\Users persists across exec calls
• Auto-reconnect with exponential backoff
• Configurable via environment variables or a client.toml config file
