Fixes
- Clicking a character to play when no game client is installed — for example after uninstalling all clients, or installing the launcher fresh in a new folder — now opens the client install dialog, then continues straight into that character once a client is ready (prompting for your password only if it isn't already saved)
- The `primal://` sign-in link now reliably opens the currently-running launcher. Previously the registered link could point at an old install path (after moving or reinstalling the launcher elsewhere); the launcher now checks and corrects this on startup
