fix(ddg): restore broad exception catch in search() to prevent pipeline crashes (#74)

PR #66 narrowed except Exception to (KeyError, ValueError, TypeError,
AttributeError) — but httpx network errors (ReadTimeout, ConnectError,
RemoteProtocolError) are not subclasses of those. Network errors during
DDG searches propagated up and crashed the entire search-news CI step.
This is a system boundary: any search failure should return [], not crash.
