Pull request overview

This PR introduces a new Source/common/ library to host shared PluginHost implementation utilities (e.g., Channel/Service/JSONRPC/VirtualInput), and adjusts Thunder runtime/process builds and project files to consume it. This effectively makes Source/plugins/ more interface-focused while moving host-side implementations into the new Common component.

Changes:

• Added new Source/common/ library (CMake + VS project) containing PluginHost “implementation support” code and a public umbrella header <common/common.h>.
• Updated Thunder and ThunderPlugin to include/link the new Common library.
• Updated CMake and Visual Studio solution/project files to add Common and to remove implementation sources from the plugins project.
