Run gofmt -w across the backend, normalising the manually-aligned := blocks to the gofmt standard. No code behaviour changes. Add Prettier (+ prettier-plugin-svelte) to the frontend with the SvelteKit default config (tabs, single quotes) so formatting is reproducible, then run it over the whole tree. Add format / format:check npm scripts and a .prettierignore (build output, generated schema.ts, static assets). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
