webworkers - initial startup helper

New docs are looking great. 👍
Was looking through webworkers and thought you might want to add a starter function which might be used when the page starts up to pre-initialise the workers so they are ready sooner.

I took this from a prior code version so it probably needs some refining, updating to 2026.1.1, and to be in a function
but something like this could be useful to add

# start workers but no handles to use and have to wait - so use ltk.schedule instead
for el in window.document.querySelectorAll("[type='py'][worker][name]"):
    print("found",el, el.id)
    print(workers, workers.id, workers.name)
    el.onload(ltk.proxy(lambda e: print("loaded",e)))
    print(dir(el))
    await workers[el.getAttribute('name')]

Start by locating the webworkers documentation entry point and comparing the current 2026.1.1 API with the older snippet in this issue. Determine whether a startup helper belongs in the docs and verify that the documented example matches the current worker-loading behavior; done means the intended pre-initialization guidance is current and usable.
