Summary

Upgrades all launcher dependencies to their latest versions and brings npm audit from 41 vulnerabilities (8 high) to 0. The only exception is vite, which stays on 7 because electron-vite 5 does not support vite 8 yet.

Changes

• Tailwind 3 to 4: braces has no patched release and only came in through Tailwind 3. Migrated with the official upgrade tool: tailwind.config.js moved into @theme in main.css, and utility classes were renamed across the templates (bg-gradient-* to bg-linear-*, shadow-sm to shadow-xs, rounded-sm to rounded-xs). Removed the unused @tailwindcss/typography and autoprefixer.
• Overrides: global-agent ^4 (drops the unpatched sprintf-js), postcss-selector-parser ^7.1.6, and js-yaml ^4 under the jest nyc config loader and the notarize plugin.
• Babel 8: removed the dropped helpers option. Babel 8 needs Node 22.18+, so test-jest.yml moves from Node 20 to 24.
• electron-vite 5: externalizeDepsPlugin replaced by build.externalizeDeps (main bundle is byte-identical).
• Electron 44, Pinia 4, js-yaml 5, uuid 14, swiper 14, vueuse 15: Jest now transforms the ESM-only Pinia, and ImportingList.vue uses a namespace import for js-yaml.

Tests

Build passes, all 308 unit tests pass, format:check is clean, and the built app starts on Electron 44 without errors. Needs a visual pass, since Tailwind 4 puts utilities in CSS layers and component <style> rules now win over them.
