- 80bd150: feat(auth): use strict OS keychain integration on macOS and Windows
Closes #623. The CLI no longer writes a fallback .encryption_key text file on macOS and Windows when securely storing credentials. Instead, it strictly uses the native OS keychain (Keychain Access on macOS, Credential Manager on Windows). If an old .encryption_key file is found during a successful keychain login, it will be automatically deleted for security.
Linux deployments continue to use a seamless file-based fallback by default to ensure maximum compatibility with headless continuous integration (CI) runners, Docker containers, and SSH environments without desktop DBUS services.
