profiling-memory-allocations

Experimental allocation profiler tracking memory allocations at guest-language level. Shows allocation sites, object types, and memory pressure patterns. Use to identify allocation-heavy locations, find unnecessary object creation, and understand memory behavior. High allocations in hot loops = optimization opportunity if escape analysis isn't eliminating them.
