feat(mvp): phase 1 - project scaffolding & tooling

Initialize SvelteKit project with Svelte 5, TypeScript strict, Tailwind CSS v4,
shadcn-svelte, Prisma + SQLite, Vitest, ESLint, Prettier. Add Docker multi-stage
build, docker-compose, and Gitea Actions CI pipeline.

 ## Handoff to Next Phase
-<!-- Filled in by the implementation agent after completing this phase. -->
+
+Phase 1 scaffolding is complete. All tooling is configured and `npm install` succeeds.
+
+**What's ready for Phase 2:**
+
+- Prisma is installed with SQLite datasource configured at `prisma/schema.prisma` — add models there.
+- `@prisma/client` is a devDependency; run `npx prisma generate` after adding models.
+- `DATABASE_URL` defaults to `file:../data/launcher.db` (see `.env.example`).
+- SvelteKit project structure is in place: `src/routes/+page.svelte`, `src/app.html`, `src/app.css`, `src/app.d.ts`.
+- `App.Locals` type augmentation defines `user` and `session` — align with the User model in Phase 2.
+- shadcn-svelte is configured via `components.json` — add UI components with `npx shadcn-svelte@latest add <component>`.
+- `src/lib/utils/cn.ts` provides the `cn()` class-merge utility used by shadcn-svelte components.
+
+**Known gaps (expected for Big Bang strategy):**
+
+- `npm run build` will fail until SvelteKit routes and server hooks are wired up.
+- `npm run check` will fail until `.svelte-kit/` is generated via `svelte-kit sync`.
+- No tests exist yet — `npm test` will pass vacuously (no test files).
