What: Add overflow guards in malloc_aligned_4k() and avoid printing to stderr on allocation failures. Why: Overflow in size calculations is a memory-safety risk; stderr output from a library is hostile to integrators. Expected impact: Deterministic NULL returns for overflow sizes and cleaner integration logs. Tests: cover overflow guard + quiet-failure semantics (tests/testDriver_malloc4k.c).
