Improve sketch run command and add TODOs

Added a TODO for sketch management in extension.ts and included additional TODOs in setupCommands.ts for using VSCode contexts. Updated the runSketch command to dispose of existing 'Sketch' terminals before creating a new one, ensuring only one active terminal per sketch run.
