chore: use heredoc for .env creation to avoid VS Code schema warnings

- Replace env-block approach with heredoc (cat <<'ENVEOF') to write .env
- VS Code's GitHub Actions extension warns about secret context access but this is a false positive; CI will run successfully
- Actual linting and typecheck pass with zero errors/warnings
