Cleanup: Wrap shared_pool debug fprintf in #if !HAKMEM_BUILD_RELEASE

Browse Source 
- Lock stats (P0 instrumentation): ~10 fprintf wrapped
- Stage stats (S1/S2/S3 breakdown): ~8 fprintf wrapped
- Release build now has no-op stubs for stats init functions
- Data collection APIs kept for learning layer compatibility
