Detailed Description

Implements OP_OPENSSL_RIPEMD160 to compute a RIPEMD-160 hash in hex.

Behavior:

• Pops one value from the VM stack and converts it to bytes by first producing its string representation with value_to_string_alloc().
• Computes the RIPEMD-160 digest via fun_openssl_ripemd160_hex() and pushes the lowercase hexadecimal string.
• On allocation or hashing failure, pushes an empty string ("").

Notes:

• Accepts any value type; non-strings are stringified first.
• Included by vm.c and executed for OP_OPENSSL_RIPEMD160.

Errors:

• Does not abort the VM; failures result in an empty string.
