feat: add multiple CMS improvements

- Add image compression to migration process
- Replace svelte-select with bits-ui (better TypeScript support)
- Fix slug input becoming date-only when cleared
- Add per-user default author preference
- Add slug redirect option when changing article URLs
- Add unpublish confirmation warning
- Add analytics page and dashboard widgets

 - Never use `as` or `any`. Let TypeScript infer types properly.
 - Never just "fire and forget". it crashes the entire server. instead, catch `.catch(console.error)` then forget, if you want to dispatch the job.

+# Coding Standards
+
+**Last Updated**: 2025-12-24
+
+## Import Order
+
+インポートは以下の順序で記述する:
+
+1. **外部ライブラリ** - `@sveltejs/kit`, `valibot`, `drizzle-orm`等
+2. **$app/*** - SvelteKitの内部API (`$app/server`, `$app/environment`等)
+3. **$lib/*** - プロジェクトの内部モジュール (階層順)
+   - `$lib/server/database/*`
+   - `$lib/server/services/*`
+   - `$lib/server/drivers/*`
+   - `$lib/shared/*`
+   - `$lib/components/*`
+4. **型インポート** - `import type { ... }`は最後
+
+### 例
+
+```ts
+// ✅ 正しい順序
+import { error } from "@sveltejs/kit";
+import * as v from "valibot";
+import { command, query } from "$app/server";
+import { requireUtCodeMember } from "$lib/server/database/auth.server";
+import { createArticle } from "$lib/server/database/articles.server";
+import { purgeCache } from "$lib/server/services/cloudflare/cache.server";
+import type { Article } from "$lib/shared/models/types";
+
+// ❌ 誤った順序
+import { createArticle } from "$lib/server/database/articles.server";
+import type { Article } from "$lib/shared/models/types";
+import { error } from "@sveltejs/kit";
+import { command, query } from "$app/server";
+```
+
+## Async/Await パターン
+
+### Fire-and-Forget パターン
+
+非同期処理を「発射して忘れる」場合、必ず`.catch(console.error)`を使用する。
+
+```ts
+// ✅ 正しいパターン
+purgeCache().catch(console.error);
+
+db.update(article)
+  .set({ viewCount: sql`${article.viewCount} + 1` })
+  .where(eq(article.slug, slug))
+  .catch(console.error);
+
+// ❌ 誤ったパターン (サーバークラッシュの原因)
+purgeCache(); // エラーがキャッチされない
+
+// ❌ 冗長なパターン
+purgeCache()
+  .then(() => {})
+  .catch(console.error);
+
+// ❌ 古いパターン (Prettierが自動修正)
+purgeCache().then(() => {}, console.error);
+```
+
+**理由**: サーバー環境では、catchされないPromiseリジェクションはサーバー全体をクラッシュさせる可能性がある。
+
+### Async/Await の統一
+
+非同期関数は一貫して`async/await`を使用する。`.then()`チェーンは避ける。
+
+```ts
+// ✅ 正しいパターン
+export const getArticles = query(async () => {
+  await requireUtCodeMember();
+  return await listAllArticles();
+});
+
+// ❌ 混在パターン (避ける)
+export const getArticles = query(() => {
+  return requireUtCodeMember().then(() => listAllArticles());
+});
+```
+
+## エラーハンドリング
+
+### Remote Functions
+
+Remote functionsでは、エラーは自動的にクライアントに伝播されるため、try-catchは不要。
+
+```ts
+// ✅ シンプルなパターン
+export const deleteArticle = command(v.string(), async (id) => {
+  const session = await requireUtCodeMember();
+  await requireArticleOwnership(session, id);
+  await deleteArticle(id);
+  purgeCache().catch(console.error);
+});
+
+// ❌ 不要なtry-catch
+export const deleteArticle = command(v.string(), async (id) => {
+  try {
+    const session = await requireUtCodeMember();
+    await requireArticleOwnership(session, id);
+    await deleteArticle(id);
+  } catch (error) {
+    throw error; // 不要
+  }
+});
+```
+
+例外: ビジネスロジックで特定のエラーを変換する場合のみtry-catchを使用。
+
+### Database層
+
+Database層では、エラーメッセージを明確にする。
+
+```ts
+// ✅ 明確なエラーメッセージ
+export async function createArticle(data: NewArticle) {
+  const [created] = await db.insert(article).values(data).returning();
+  if (!created) throw new Error("Failed to create article");
+  return created;
+}
+
+// ❌ 曖昧なエラー
+export async function createArticle(data: NewArticle) {
+  const [created] = await db.insert(article).values(data).returning();
+  return created; // undefinedの可能性
+}
+```
+
+## 命名規則
+
+### ファイル命名
+
+- **Remote Functions**: `*.remote.ts`
+- **Server Functions**: `*.server.ts`
+- **Shared Logic**: `*.ts` (サフィックスなし)
+- **Tests**: `*.test.ts`
+- **Types**: `types.ts` または `schema.ts`
+
+### 関数命名
+
+- **Remote Query**: 名詞形 (`getArticles`, `getMember`)
+- **Remote Command**: 動詞形 (`saveArticle`, `editMember`, `removeProject`)
+- **Server Functions**: 動詞形 (`listArticles`, `createMember`, `updateProject`)
+
+```ts
+// Remote Functions (DAL)
+export const getArticles = query(async () => ...);
+export const saveArticle = command(..., async (data) => ...);
+
+// Server Functions (DB)
+export async function listArticles() { ... }
+export async function createArticle(data: NewArticle) { ... }
+```
+
+## Valibot バリデーション
+
+### Picklist の使用
+
+列挙型の値は`v.picklist()`を使用する。
+
+```ts
+// ✅ 型安全なpicklist
+const PROJECT_CATEGORY_VALUES = [
+  "active",
+  "ended",
+  "hackathon",
+  "festival",
+  "personal",
+] as const satisfies readonly ProjectCategory[];
+
+const categorySchema = v.picklist(PROJECT_CATEGORY_VALUES);
+
+// ❌ 型安全でないパターン
+const categorySchema = v.picklist(["active", "ended", "hackathon"]);
+```
+
+## フォーマット
+
+### インデント
+
+- **タブ文字**を使用 (Prettier設定: `useTabs: true`)
+- スペースは使用しない
+
+### 行の長さ
+
+- 最大120文字 (Prettier設定: `printWidth: 120`)
+- 長いインポートや関数呼び出しは自動で折り返される
+
+### セミコロン
+
+- 常にセミコロンを使用 (Prettier設定: `semi: true`)
+
+### クォート
+
+- ダブルクォートを使用 (Prettier設定: `useTabs: true`)
+
+## ツール
+
+### 自動フォーマット
+
+```sh
+bun tidy  # type-check + test-check + biome + prettier
+bun fix   # biome + prettier のみ
+```
+
+### 個別チェック
+
+```sh
+bun type-check    # TypeScript型チェック
+bun test-check    # 単体テスト
+bun lint-check    # Biomeリント
+bun format-check  # Prettierフォーマット
+```
+
+## 検証ルール
+
+コミット前に必ず以下を実行:
+
+1. `bun type-check` - エラー0であること
+2. `bun tidy` - エラー・警告0であること
+
