Permission Denied on auth.json

• Root Cause: ~/.omniedge/auth.json was owned by root after running CLI with sudo, preventing the desktop app from reading it.
• Fix: chown_to_real_user() detects the real user via $SUDO_USER and corrects file ownership after writes.

Broken Pipe on start_vpn IPC

• Root Cause: connect_with_token() blocked synchronously in the helper's IPC handler, causing the Unix socket connection to time out.
• Fix: tokio::spawn for async VPN startup; desktop app polls connection status every 500ms instead of waiting for a single response.

Nucleus Returns 0 Peers

• Root Cause: get_recent_peers() filtered by joined_at.elapsed() < 90s, returning 0 peers when no recent joins occurred.
• Fix: Returns all peers for new registrations + API-seeded peer discovery ensures immediate connectivity.
