Buffer Overflow in Freestanding Runtime: How Unsafe strcpy() Puts Bare-Metal Systems at Risk

A critical buffer overflow vulnerability was discovered in the freestanding runtime's custom string library, where `strcpy()` and `memcpy()` implementations lacked any bounds checking whatsoever. In a bare-metal or kernel-like environment with no OS-level memory protection, this flaw could allow an attacker to overwrite adjacent memory regions — including function pointers and security-critical state — with arbitrary data. The fix introduces a safe `strlcpy()` implementation that enforces destin
