fix: clean JSON output for cost command in CI

- Suppress Logger messages when format is JSON to avoid polluting output
- Use tail to skip dotenv message and DOTENV_QUIET env var in CI
- This resolves jq parsing errors in GitHub Actions workflow
- JSON output is now clean and parseable by automation tools
