Bug: Missing SIGHUP handler leaves daemon uncleanly terminated

Location: packages/hub/src/daemon.ts lines 203-211

Problem: The daemon registers handlers for SIGTERM and SIGINT but not SIGHUP. When a user closes the terminal window on Windows, SIGHUP is sent but cleanup() is never called, leaving:

• Orphaned Windows Firewall rules
• Leftover hub.pid and hub.json files
• Stuck sleep prevention flag
• Orphaned node processes

Suggested fix: Add SIGHUP handler alongside existing SIGTERM/SIGINT:

process.on("SIGHUP", () => {
  cleanup();
  process.exit(0);
});

Environment: Windows 11 + WSL2 (Hyper-V), Node.js 20.x
