scripts/build-wsl2-image.sh — idempotent setup for governed jumphost.
Installs: gsh, kubectl, helm (all to ~/.local/bin, no sudo needed)
Configures: corpus directory, SSH aliases (dev.gsh, stg.gsh),
.gshrc environment defaults
Export: --export flag prints wsl --export/import commands
No sudo required for gsh/corpus/config setup. System packages
(curl, git, etc.) prompt for manual install if sudo unavailable.
