v0.28.0

Release Notes

Summary

OpenMark 0.28.0 focuses on preview source navigation hardening. It includes shared preview source navigation helpers now live in src/previewSourceNavigation.ts so click targeting, source range parsing, and line estimation can be tested outside App.tsx, regression tests now cover source range extraction for headings, preserved blank lines, blockquotes, nested lists, tables, and fenced code blocks rendered from real Markdown, and preview source navigation now rejects invalid source metadata and keeps links and native controls from being intercepted by source-jump handling.
