Changes: - Save issue-prefix in config.yaml when using --no-db mode (previously only saved in database which doesn't exist in no-db mode) - Add config.ResetForTesting() to allow reloading config in tests - Simplify test to verify config values rather than execute subsequent commands (cobra's flag caching makes multi-Execute() testing complex) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
