Strip spurious leading slash from Windows drive-letter paths (/D:/foo → D:/foo) in parseLocalFileTarget so that workspace-relative comparison succeeds and local files can be opened correctly. Display the normalized path in the confirmation dialog. Internationalize all link safety dialog and toast strings across 10 locales.
Import KaTeX CSS in layout.tsx to ensure math formulas display correctly
in both dev and production modes. Convert LaTeX-style `\[...\]` / `\(...\)`
delimiters to `$$...$$` / `$...$` since remark-math only supports dollar
sign delimiters, fixing formula rendering for agents like Codex.
