Port frontend from Vue to Svelte (WIP in separate folder, many bugs) (#964)

* Make `tauri build` just work * Move folder: frontend/wasm -> wasm * Create SvelteKit project with 'npx create-svelte' * Move wasm-communication into seperate npm package * Use wasm-pack directly and pack package.json * Got it to work * Add primitive build script for wasm npm module * Fix wasm build script (python) * Clean up glue code * Rewrite wasm build script in node.js * Add serde-reflection to trace types * Add traced types * Generate typescript (.d.ts) from Rust types * Update .d.ts * Finalize TS types * Add script to update .d.ts * Add watch command to build wasm-bindgen * Make wasm work again * Add sass; fix build script for windows * Describe requirement for wasm-pack * Add license * Copy and reorganize vue components * translate LayoutCol.vue * Split app.scss into pieces * Translate LayoutRow.svelte * Rename scss files * Fix compile issues on Windows * WIP port TitleBar * Support classes for LayoutCol/Row * Restructure based on Vue codebase * Port all components in window folder * Port FloatingMenu * Port Document panel component * Update readme after folder move * Update typegen: print discriminant by default * Update typegen: Merge from branch 'tailwind' 4f14fedb Fixes bigint & bytes * Made Vue/webpack/eslint to accept wasm package at new location This is quite a hack. Those two packages are both named the same. Yes, it's an npm package inside another npm package. - frontend/src/wasm-communication/ - frontend-svelte/glue/ 'wasm/pkg/index.js' imports the correct one registered when linking. * Port LayerTree * Port NodeGraph * Port Properties * Port components in /floating-menus * Finish porting all Vue -> Svelte components * Change import prefix * Revert type generation * Revert moved wasm folder * Revert all of @locriacyber's work on this branch - Remove Vite and restore Webpack - Remove SvelteKit - Remove everything except the components I ported to Svelte - Restore all frontend files from Vue code, now altered for Svelte * Convert Vue's 'reactive' and 'provide' to Svelte's stores and contexts * Fix event emitting and bi-di data flow * Undo removal of 'update:' events * Fix 'update:' event dispatching * Fix usage in parent of bi-di component props * Fix component typing, more progress towards no errors * The page builds and opens! * Add loading spinner and remove postcss dependency * Make the basics of document editing work * Fix rebase history Co-authored-by: Locria Cyber <74560659+locriacyber@users.noreply.github.com>
