fix: suppress linkifyjs already-initialized warnings in console

[j4rviscmd]

Summary

• Add inline script in index.html to suppress linkifyjs: already initialized console warnings
• The override runs before Vite pre-bundled chunks capture console.warn, ensuring it applies to the dependency code
• Workaround for [Bug]: linkify.init not called causing warnings in logs ueberdosis/tiptap#5450 — @tiptap/extension-link registers custom protocols in onCreate() after linkifyjs has already been initialized by the autolink plugin

Test plan

• Run npm run tauri dev and verify no linkifyjs: already initialized warnings in DevTools console
• Verify link autolink still works (type a URL in the editor)
