test: add 67 tests for untested shared/common.sh helpers (#978)
Cover 8 functions that had zero test coverage: - log_install_failed: actionable guidance for agent install failures (added across 126 scripts) - ensure_jq: cross-platform jq installation - get_cloud_init_userdata: cloud-init template structure and content - _multi_creds_validate: credential validation with env var cleanup on failure - check_python_available: dependency check with install guidance - calculate_retry_backoff: exponential backoff with jitter bounds - verify_agent_installed: agent command verification with diagnostic output - _log_diagnostic: structured error reporting with causes and fixes - _generate_csrf_state: CSRF token generation with multiple backends - register_cleanup_trap / track_temp_file / cleanup_temp_files: temp file lifecycle Agent: test-engineer Co-authored-by: A <6723574+louisgv@users.noreply.github.com> Co-authored-by: Claude Haiku 4.5 <noreply@anthropic.com>
