Fix YARA compiler move issue in error path

Browse Source 
When add_rules_str() fails, the compiler is already consumed.
Changed from 'continue' to 'return Err' to avoid trying to use
the moved compiler in the next loop iteration. This properly
handles the builder pattern where the value is consumed on error.
