Detailed Description

Implements the OP_WRITE_FILE opcode for writing to a file in the VM.

This file handles the OP_WRITE_FILE instruction, which writes data to a file. The file path and data are popped from the stack, and a success/failure flag is pushed back.

Behavior:

• Pops the file path and data from the stack.
• Writes the data to the file.
• Pushes 1 (success) or 0 (failure) onto the stack.

Error Handling:

• Exits with an error if the file path is invalid or the file cannot be written.

Example: // Bytecode: OP_WRITE_FILE // Stack before: ["file.txt", "data"] // Stack after: [1]
