🧪 Organize benchmark tests and run simulation in C++

🤖 AI text below 🤖

Description

Organize C++ generator tests and Python binding tests by benchmark family. Share generation, QCO compilation, sampling, and jeff round-trip checks in the native test utilities.

Run multiplexer, QFT, and QPE sampling checks in C++, using the default compiler pipeline and DD sampler. Include the existing bounded f64 phase-table support needed for direct QPE execution. Python tests cover typed options, JSON round trips, exceptions, and program bindings; dedicated simulator-binding tests already cover the public sampling API.
