    analyzer: mark epath_finder with DISABLE_COPY_AND_ASSIGN [PR99614]
    
    cppcheck warns that class epath_finder does dynamic memory allocation, but
    is missing a copy constructor and operator=.
    
    This class isn't meant to be copied or assigned, so mark it with
    DISABLE_COPY_AND_ASSIGN.
