Shift+E enters an emoji quick-input mode backed by the emoji_pinyin index in
others.db, supporting full pinyin (xiaolian), abbreviated pinyin (xl), English
words (laugh), and shuangpin codes (Xiaohe xnlm expands to xiaolian).
- src/emoji/emoji_query.{h,cpp}: prefix lookup over emoji_pinyin with
shuangpin->quanpin expansion driven by the active scheme
- event_listener: Shift+E trigger, composition helpers, candidate branch, and
direct commit through the new CandidateSource::Emoji
- config: [utility] emoji_mode toggle wired through settings_app / webview2
- tests: emoji_query coverage for full/abbrev pinyin, English, Xiaohe shuangpin
- engine submodule: CandidateSource::Emoji (core/word_item.h)
