Replace struct timespec (arch-dependent long/time_t) with fixed-width int64_t pairs in ft_shared_s so that 32-bit and 64-bit processes interpret the same shared memory layout identically. Fix ftruncate calls that allocated sizeof(uint64_t) (8 bytes) instead of sizeof(struct ft_shared_s) (64-80 bytes) for the shared memory region. Fix munmap in ft_cleanup using the wrong size. Add struct layout test and cross-process shared memory functional test.
