Toolchanger printers with 4 tools were incorrectly treated as dual-nozzle (IDEX-style) printers in AMS Sync. So I was locked to just tool 1/2.

Adjusted AMS Sync to use dual-nozzle logic only for true 2-nozzle setups (nozzle_nums == 2 and filament_map in {1,2}), and route 3+ tool toolchangers through the generic mapping flow so all tool IDs are handled correctly.
