Fuzzes the CPython mmap C module (Modules/mmapmodule.c) by creating a temporary file seeded with fuzzed bytes and memory-mapping it read/write. Drives a sequence of up to ten operations — find, rfind, read, readline, seek, getitem, write, setitem, move, and flush — with fuzzed offsets, lengths, needles, and byte values to exercise bounds handling and buffer management in the native implementation.
