Adds an associate circuit judge to the 23rd judicial circuit

This bill adds two full circuit judge positions and one associate circuit judge position to Jefferson County's 23rd judicial circuit by converting two existing commissioner roles into judicial positions. Specifically, it redesignates the family court commissioner (as Division 11) and treatment court commissioner (as Division 12) as full circuit judges starting January 2007, with both elected in 2006. It also creates a new associate circuit judge position to be appointed by the governor until 2029, with a subsequent election in 2028. The changes directly affect Jefferson County's court staffing structure under Missouri law.
