Studio is the Ch∆In product's GUI, not a F∆I-vendor app. Rename the Flutter package, all package: imports, and the build identity across platforms: linux/windows CMake BINARY_NAME + project, Windows Runner.rc fields, macOS PRODUCT_NAME / bundle id (ai.flemming.chain.chainStudio) / .app + scheme BuildableName. Update the client-SDK + flow-editor deps to their renamed chain_* packages (path + git URL). Company/copyright fields now read Flemming.AI. flutter analyze: clean.
