Detailed Description

Implements the OP_TO_STRING opcode for converting values to strings in the VM.

This file handles the OP_TO_STRING instruction, which converts a value of any type into its string representation and pushes the result onto the stack.

Behavior:

• Pops a value from the stack.
• Converts the value to a string based on its type:
  • Integers: Convert to decimal string (e.g., 42 → "42")
  • Strings: Return a copy of the string
  • Arrays: Convert to "[array n=<length>]"
  • Maps: Convert to "{map n=<length>}"
  • Functions: Convert to "<function@<address>>"
  • Nil: Convert to "nil"
• Pushes the resulting string onto the stack.

Error Handling:

• Exits with an error if memory allocation fails during string creation.

Example: // Bytecode: OP_TO_STRING // Stack before: [42] // Stack after: ["42"]
