v3.1.2

New features & improvements

• Reorganized the renderer, desktop, webserver, core, and shared contracts into dedicated workspaces.
• Published a public documentation website (Docusaurus) at piratuks.github.io/invoice-builder, auto-built and deployed to GitHub Pages on every push to main, with guide pages reorganized into flat per-screen docs and dedicated screenshot/example asset folders.

Bug fixes

• Fixed the packaged Windows/Linux/macOS desktop app failing to start with "Cannot find module 'sqlite3'", caused by the packager silently excluding all node_modules from the build and the native sqlite3 binary not being unpacked from the app archive.
