Detailed Description

Implements the OP_JUMP_IF_FALSE opcode for conditional jumps in the VM.

This file handles the OP_JUMP_IF_FALSE instruction, which jumps if the top stack value is falsey (0, false, nil, etc).

Behavior:

• Pops condition value from stack
• Jumps to operand IP if falsey
• Continues normally if truthy

Used for:

• If statements
• While loops
• Logical expressions
