fix: use RUNNER_TEMP instead of mktemp in GitHub Actions

- Replace mktemp calls with RUNNER_TEMP when available in CI environment
- Ensures temporary files are created in GitHub Actions designated temp directory
- Fallback to mktemp for local development environments
- Prevents potential permissions issues with system temp directories
