Rename task dirs to 01_info_leak through 07_heap_aslr following a
standard learning order (info leak → ROP → fmtstr → heap overflow →
UAF → LFH grooming → ASLR bypass). Remove bof_basic, demos,
heap_segment, and template directories. Strip debug symbols from all
compiled challenge binaries and remove all .exe files from the tree.
Strip all explanatory comments from solve scripts.
