NOT GREEN. resolveWait marks a context-parked waiter ready and arms a pump
instead of resolving a promise nobody awaits.
The doc records the measured correction: DoRun parks the MAIN stack every
frame in wxWasmYieldToBrowser, which doc 21 called safe-by-construction only
because dispatch also ran there. With the scheduler swapping contexts from the
tick, those interleave over one currData - overlapped-wake, the exact class
this work exists to remove. So the main loop must become a context (D5) and
the bridges (E) join the same flip: D5+D+C+B+E land together.
