fix(win): replace std::hex/std::dec with ipc::spec for MinGW compatibility (issue #171)

Browse Source 
Replace I/O manipulators (std::hex, std::dec) with ipc::spec in log
statements. The ipc::fmt system does not support std::iostream
manipulators, which caused compilation failures under MinGW.

Changed files:
- src/libipc/platform/win/mutex.h (lines 78, 96)
- src/libipc/platform/win/semaphore.h (line 71)

The format spec "#x" produces output like "0x102" which matches
the original behavior:
- # flag adds the "0x" prefix automatically
- x outputs lowercase hexadecimal

Fixes: #171
