Reorganize like upstream: library at root (docking/dragdrop/debug tools merged into imgui.lua, tabs into imgui_widgets.lua), single imgui_demo.lua, backends/, fonts/, examples/, docs/; --no-demo build

#!/usr/bin/env python3
# Bundles imgui/*.lua + backend into ONE ModuleScript: build/ImGui.luau
# Bundles the root *.lua (library + imgui_demo.lua), backends/ and fonts/ into ONE ModuleScript: build/ImGui.luau
# --no-demo: library only (imgui_demo.lua left out, like not compiling imgui_demo.cpp)
# Why: ModuleScripts don't share globals, and the setfenv() alternative turns off Luau's fast paths / native codegen.
# Each source file becomes a function in __FILES; IM_INCLUDE(name) runs it once and caches the result.
# The module returns a table with every global the library defines (ImGui, ImVec2, ImGuiConfigFlags, ImGui_ImplRoblox, ...).
