SQSCANGHA-140 Add fallback keyserver for GPG signature verification
Add hkps://keys.openpgp.org as fallback keyserver to improve reliability when the primary keyserver (keyserver.ubuntu.com) is unavailable due to outages, network issues, or rate limiting. Changes: - Extract key import logic into tryImportKey() helper function - Implement automatic fallback in importSonarSourceKey() - Add comprehensive error messages showing both keyserver failures - Add integration tests verifying fallback mechanism - Update JSDoc to document fallback behavior - Rebuild distribution The implementation maintains backward compatibility with no changes to function signatures or default behavior. Primary keyserver is always attempted first. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
