Repomon Desktop (preview)

Rolling preview build of the Repomon desktop app, for testing. The installed app
auto-updates from this release (updates are cryptographically signed; the OS-level
code signature is not set yet, so first install shows a Gatekeeper/SmartScreen prompt).

Requires a working repomon/repomond setup (tmux on macOS/Linux).

• macOS: universal dmg. Right-click the app and choose Open on first launch
  (or xattr -dr com.apple.quarantine /Applications/Repomon.app).
• Linux: AppImage (auto-updates), deb, or rpm. Requires tmux.
• Windows: NSIS installer. Bundles the daemon and per-agent ConPTY host (no tmux needed).
