fix: carry digit context into the following word

 ### Fixed
 
+- Digits now supply their context to the following word, including after another word, so units such as `10cm` and `10fps` keep their Latin reading. Deleting an owned suffix preserves its numeric origin, while context changes and internal word splits prevent that origin from leaking to unrelated text.
 - Explicit language corrections on unchanged input and context now learn against the reading actually shown. Hidden final scoring no longer prevents those corrections from being learned or treats a return to the original reading as a new correction. Existing scoring after editing a forced word and ordinary confirmation behavior are preserved.

 ### 수정
 
+- 다른 단어 뒤에 입력한 숫자를 포함해, 숫자 문맥이 바로 뒤 단어에 전달되도록 고쳐 `10cm`, `10fps` 같은 단위 입력이 라틴 표기를 유지합니다. 조합 중인 접미사를 지웠을 때는 숫자 문맥을 보존하고, 문맥 변경이나 내부 단어 분리 뒤에는 무관한 입력에 이어지지 않도록 했습니다.
 - 입력 문자열과 문맥이 유지된 명시적 언어 교정은 실제로 화면에 보였던 언어를 기준으로 학습합니다. 확정용 재판별 때문에 교정을 학습하지 못하거나, 원래 표시로 돌아온 선택을 잘못 학습하던 문제를 고쳤습니다. 교정 후 입력을 편집한 경우의 판별과 일반 확정 동작은 유지합니다.
