Subcommands gain one/two-letter aliases (dl, i, e, v, h) alongside
their full names. CLI-owned chrome - top-level usage, per-subcommand
usage lines, progress messages, and the license prompt - now goes
through internal/i18n, an env-driven message catalog (MSVC_GO_WINE_LANG,
falling back to the standard LC_ALL/LC_MESSAGES/LANG locale variables)
with English and Russian translations. Deeper error text from internal
packages stays in English.
Also refreshed the top-level usage text, which hadn't kept up with
--with-wdk/--list-workloads/--list-components/--print-deps-tree.
