Interlanguage CJK Mathematical Notation Backend

A dedicated, independently citable distribution of the evidence-backed CJK mathematical document backend first published inside the Interlanguage methodology sidecar. Version 1.1.0 preserves the complete report-v2 contract; adds opt-in typed semantic, locale-layout, notation-standard, PDF/accessibility, and provenance report states; and adds revision-2 source-force evidence records while keeping Chinese, Japanese, and Korean terminology and prose independently governed.
