amitwh efca458495 fix(deps): clear all npm audit vulnerabilities (27 → 0)
- Remove unused docx4js (only a stale comment referenced it); drops the
  vulnerable transitive xml2js prototype-pollution chain
- Upgrade sharp 0.34 -> 0.35.4 for the libvips CVEs (GHSA-f88m-g3jw-g9cj);
  resize/format API surface unchanged, @img/@napi-rs asarUnpack globs still
  match the new prebuilt layout
- npm audit fix for the rest: electron 41.10.7 (protocol/iframe fixes),
  electron-builder chain (AppImage search-path + updater token leak),
  dompurify 3.4.14, mermaid 11.17.2, tar (PAX parsing, critical), tmp,
  js-yaml, brace-expansion, browserslist, fast-uri, form-data, ip-address,
  nanoid, fflate, @xmldom/xmldom, @babel/core and others

613/613 tests green; lint clean; npm audit reports 0 vulnerabilities
