Move runtime frame hiding into helper func
Call it `hide_runtime_frames()` and stick all the lines from the top of the `._debug` mod in there along with a little `log.devx()` emission on what gets hidden by default ;) Other, - fix ref-error where internal-error handler might trigger despite the debug `req_ctx` not yet having init-ed, such that we don't try to cancel or log about it when it never was fully created/initialize.. - fix assignment typo iniside `_set_trace()` for `task`.. lelruntime_to_msgspec
