Patch Changes

• 105d66d73529812a8eddc0847891e7f0c574e129 #4713 Thanks @xaviergonz! - perf: reduce memory used by large, mostly unobserved state. intercept / observe handler arrays are allocated at their exact size, an observable's internal observers Set is released once its last observer leaves, observable objects created with the same deep / autoBind options share one default annotation instead of allocating their own, and endBatch() skips the unobservation pass when nothing is pending.
