Subject: [PATCH] Set CMAKE_BUILD_TYPE=Release for FreeRDP production builds.

Without an explicit build type, CMake defaults to an empty configuration
which leaves WINPR_ASSERT runtime assertions enabled. These assertions
call abort() on unexpected conditions, silently killing guacd child
processes without any log output. Setting Release mode disables the
assertions, enables compiler optimizations, and matches how Linux
distributions package FreeRDP.
