fix: return empty string instead of null on glob failure in directory glob

Browse Source 
The tool_function_directory_glob function previously returned NULL when the glob
pattern failed to match, causing a null pointer dereference in the user profile
avatar loader when it attempted to process the result. Changed the return value
to an empty string to ensure callers always receive a valid pointer.
