The Chinese copy was mixed: the nav read 智能体 while every other string kept
`preset` untranslated (本会话的 agent preset, 新建 preset, preset 名称).
It is now one register throughout — Agent stays, preset becomes 预设, the
standard Chinese UI word for a named, switchable configuration bundle, which
is what a preset is when a session picks one.
UI copy only. The docs keep `agent preset` as the technical term for the
composition and the `agent-presets` plugin.
