* fix(hopper): preserve caller abort reasons on cancellation Hopper cancellation dropped the caller's abort reason, and the typed error treated an explicit undefined cause as omission. Retain the exact reason at the request queue, startup, socket, and launcher boundaries. Co-authored-by: morluto <morluto@users.noreply.github.com> * style(hopper): format launcher cancellation return oxfmt rejects the wrapped abort return in HopperApplicationLauncher.
