| txt-chapter-measure-word-4658 | TXT import detected 第一封信/第四本书 (量词 prose) as chapters; split units into strong vs weak (separator-required) |

#4658 (目录检测优化): TXT→EPUB chapter detection (src/utils/txt.ts createChapterRegexps('zh'), first regex) wrongly surfaced prose lines as TOC entries:
第一封信。/第七封信(the Nth letter) — measure word封was a chapter unit.第四本书记载着锤法，来自孙家，可惜对秦铭用处不大了…(the fourth book + full sentence) — measure word本.
Root cause: the unit class [章卷节回讲篇封本册部话] treated 量词 (measure words) the same as real chapter units, and allowed a title to attach DIRECTLY after the unit (封信, 本书).
Fix = split units into two tiers in the regex:
- Strong
[章节回讲篇话]— may carry an attached title (第一章天地初开), unchanged:(?:[：:、 \(\)0-9]*[^\n-]{0,36}). - Weak / 量词
[卷本册部封]— title MUST be introduced by a separator or the line ends, i.e. the char after the unit must be[：:、 \(\)](or boundary), never a bare noun:(?:[：:、 \(\)][：:、 \(\)0-9]*[^\n-]{0,36})?.
So 第一封 致读者 / 第一本 标题 / 第二部 中篇 / 第一卷 起始篇 / standalone 第一本\n still match (existing tests rely on this); 第一封信 / 第四本书... do not. Weak set = the same units used by the isVolume regex (卷|本|册|部) plus 封. (?!\S) end-anchor does the rejection by backtracking when a noun follows. Tests in __tests__/utils/txt.test.ts ("measure-word false positives", two e2e). Not touched: 节 (kept strong despite 第三节课 risk — not in scope).
