A target process may have a read-only whole-file mmap() of a system library (e.g. libc.so) at file offset 0 before the real, executable loaded image in /proc/<pid>/maps. Matching the first file_offset == 0 mapping resolves imports and IFUNC resolvers into the non-executable file mapping. Delegate candidate selection to ProcMapsSnapshot.find_module_by_path(), which scores file_offset == 0 candidates by executable segments, and bound copy_from_target() to the selected mapping's contiguous instance.
