Persist login, but still a users choice though

Let's ask users right after login if they want to preserve there access. If they want they we need to save it directly in a encrypted file for security.

No files or tests are specified in the issue. Start by finding the CLI login/auth flow entrypoint and any existing credential or config persistence path in the code. Check README/startup docs for where authentication is wired, then add a post-login opt-in step and write/reload access data only when enabled, using the encrypted-storage mechanism in use. Done means login preference is persisted securely and honored on next launch, or login remains unchanged when declined.
