New version of run-hurd.sh:
https://ion.nu/tmp/run-hurd-2026-03-16.sh.txt
I found where -M q35 was useful, it's for RAM of 4GB or higher.

With -M q35 up to 16GB works, past that it still bootloops.
Along with conditionally adding -M q35 this version has an -m option to
specify the amount of RAM.
It also has a -v option to set the display options (e.g. vnc, curses),
a -s option to set the ssh forwarding port,
some basic dependency checking that exits with a helpful message, and
some general tuning
