Add core fiber functionality including Fiber.create, Fiber.run, Fiber.yield primitives with value passing between fibers. Introduce PRIM_RUN_FIBER result type for interpreter loop, add caller field to ObjFiber struct for yield resumption, and update GC marking to traverse fiber caller chains. Modify wrenNewFiber to accept a function/closure argument and initialize the first call frame. Add debug stack printing with fiber pointer. Include test suite covering fiber creation, run, yield, value passing, type checking, and caller resumption.
