cd repo && git status → ["git"]) and wrappers
(sudo make install → ["make"]) are skipped, and pipeline formatting
helpers are dropped when a more meaningful command remains
(git log | head -3 → ["git"]). Clients use it for the command-card
title (e.g. “Command git”) instead of re-parsing the command themselves.
Like [TerminalCwdMeta], this struct is designed to be merged standalone
into any tool call’s _meta via [Meta::merge_into].
