Detailed Description

Implements the OP_TAN opcode using C99 math.h tan().

VM opcode snippet included by vm.c. Provides tangent function.

Behavior:

• Pops one numeric operand (int or float) from the stack.
• Computes tan(x) in double precision.
• Always pushes a VAL_FLOAT result.

Stack effect:

• Pop: x
• Push: tan(x)

Types:

• Accepts VAL_INT and VAL_FLOAT; others cause a runtime error.
