ComfyUI's locales/ feature only covers node definitions, so the custom painting
controls and parameter panel are translated here instead, by reading Comfy.Locale.
English stays the built-in default, which keeps the Manager listing usable for
the general audience. When the ComfyUI language is Chinese the canvas buttons and
the parameter panel labels switch to Chinese as well; any key without a
translation falls back to English.
Node display names, category, descriptions, tooltips and all frontend labels are
now English so the nodes are usable for the general Manager audience. Node class
IDs, parameter identifiers and enum values are unchanged, so existing workflows
stay compatible. Also documents how this pack differs from ComfyUI's built-in
modal mask editor and Painter node.
