Pull Request Overview

This PR reduces Boost usage across the codebase to simplify builds and improve portability by replacing Boost components with standard library equivalents and platform APIs.

• Replace Boost date_time/chrono with std::chrono and C time APIs in time-related modules and profiler.
• Replace Boost interprocess named_mutex with Win32 named mutexes and POSIX named semaphores for IPC flags; remove Boost linking from CMake/vcxproj.
• Replace Boost utilities (gcd, ibeta, endian) with std::gcd, a local incomplete beta implementation, and custom byte-swap helpers.

std::vector is used but is not included on non-Windows builds; this will fail to compile. Add #include near the other standard headers.

Suggested change

	#include <sys/types.h>
	#include <sys/types.h>
	#include <vector>

std::size for raw arrays requires in C++17; it's not included here and may cause build failures. Simpler and clearer: initialize size with MAX_COMPUTERNAME_LENGTH + 1 and avoid std::size.

[nitpick] The previous implementation used local time; switching to UTC changes Calendar's default month/year in locales west/east of UTC around midnight. To preserve prior behavior, derive y/m from local time (e.g., using std::time + localtime_r/s).
