Narrow the ever contraction guard to a preceding e or i

[owjs3901]

국립국어원 점자상담 337번 회신(2026-09-12)을 반영한다.

통일 영어 점자 규정 10.7.4에는 'ever'의 첫 글자 'e'에 강세가 오고 그 앞에 'e'나 'i'가 오지 않는 경우 어두 약자 5점, 15점(두 칸)을 사용하도록 정하고 있습니다.

기존 가드는 앞 글자가 모든 모음일 때 약자를 막았으나, 규정이 막는 것은 e 와 i 뿐이다.

근거는 fixture 안에 이미 있다. rule_10_7_2.json 의 whosesoever 는 o 뒤에서 약자를 쓴다(⠘⠱⠎⠕⠐⠑). e/i 로 막히는 쪽도 fixture 가 확인한다 — believer(i), thievery(i), McKeever(e) 는 모두 철자다.

검증

• 규정 fixture 5141/5141
• 말뭉치 455,395/467,121 (97.49%) — 변동 없음. a/o/u + ever 조합이 말뭉치에 없다
• cargo test --release -p braillify 4,984 + 541 통과
• clippy 통과

회신의 나머지 절반(강세 판정)은 CMUdict 에 없는 상표 이름에서 확인할 방법이 없어 손대지 않았다. Weverse 를 약자로 돌리면 같은 꼴인 eversion/reverify 가 함께 깨지는 것을 측정으로 확인했다.
