constexpr auto	stlab::main_executor
	Runs void() noexcept tasks on the process main thread (Qt, libdispatch, or Emscripten as configured).

Detailed Description

Main-thread / UI-thread executor (Qt, libdispatch, Emscripten, etc.).

Tasks submitted to main_executor run on the application's main loop (Qt event loop, libdispatch main queue, or Emscripten main loop when configured). Tasks are executed in submission order.

Destroying main_executor does not destroy the underlying UI/main loop; submitted work still runs. A main executor is not implemented for Windows unless STLAB_MAIN_EXECUTOR selects Qt.
