Luau types: generated typed entry module build/ImGuiTyped.luau (requires the bundle as child Impl); Rojo/Wally use it

 # 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, ...).
+# Roblox target also writes ImGuiTyped.luau (types + require(script.Impl), see tools/gen_types.py).
