feat: extract bytecode dumpInstruction into new wren_debug module Move the dumpInstruction function and its associated opcode printing logic from wren_vm.c into a dedicated wren_debug.c source file with a corresponding wren_debug.h header. Add the new source file to the Xcode project build configuration.

feat: implement closures with upvalue support and statement/expression separation Add closure objects that wrap functions with captured upvalues, enabling first-class closures that close over local variables from enclosing scopes. Introduce new bytecode instructions (CODE_CLOSURE, CODE_LOAD_UPVALUE, CODE_STORE_UPVALUE, CODE_CLOSE_UPVALUE, CODE_RETURN) and a CompilerUpvalue tracking system with a MAX_UPVALUES limit of 256. Refactor the grammar to strictly separate statements from expressions, fixing a bug where block expressions incorrectly popped locals while temporaries remained on the stack. Rename internal functions (wrenCallFunction, wrenDebugDumpInstruction, wrenDebugDumpStack) and add Upvalue allocation, closure creation, and debug dump support for the new instructions.

feat: promote Fiber from raw struct to heap-allocated ObjFiber with GC support Refactor the VM's fiber representation from a stack-allocated `Fiber` struct embedded in `WrenVM` to a full `ObjFiber` object managed by the garbage collector. This includes adding the `OBJ_FIBER` object type enum, a `wrenNewFiber` allocation function, a `markFiber` traversal routine for GC marking, and updating all internal APIs (`DEF_FIBER_NATIVE`, `wrenDebugDumpStack`) to use `ObjFiber*` instead of `Fiber*`. The `Fiber` struct definition and its associated `CallFrame` type are moved from `wren_vm.h` into `wren_value.h`, and the `STACK_SIZE`/`MAX_CALL_FRAMES` constants are relocated accordingly. Additionally, the `vm->fiber` singleton pointer is removed, the `vm->unsupported` sentinel value is eliminated (replaced by returning `NULL_VAL` for invalid numeric operands), and the `wrenInterpret` function is temporarily removed. The `wrenNewClass` function's metaclass pinning order is also corrected to prevent premature GC collection.
