Added tons of opcode documentation, changed license to ISC and a lot of file refactoring.

+/**
+* @file make_array.c
+ * @brief Implements the OP_MAKE_ARRAY opcode for creating arrays in the VM.
+ *
+ * This file handles the OP_MAKE_ARRAY instruction, which pops `n` values from the stack,
+ * creates an array from them, and pushes the resulting array back onto the stack.
+ *
+ * Behavior:
+ * - Validates the number of elements (`n`) to ensure it is non-negative and within stack bounds.
+ * - Allocates temporary storage for the array elements.
+ * - Constructs the array using `make_array_from_values`.
+ * - Frees temporary storage and pushes the array onto the stack.
+ *
+ * Error Handling:
+ * - Exits with an error if `n` is invalid or if memory allocation fails.
+ *
+ * Example:
+ * // Bytecode: OP_MAKE_ARRAY 3
+ * // Stack before: [1, 2, 3]
+ * // Stack after: [[1, 2, 3]]
+ *
