Jeffery f44200f543 feat: 完成 B 群組 — 資料層與核心領域模型

- 導入 Prisma 7.9.1 + SQLite（better-sqlite3 driver adapter），prisma.config.ts 管理連線設定
- 完整資料模型：User／Work／Character／CharacterAlias／EpisodicMemory／SemanticMemory／
  ProceduralRule／EmotionState／Relationship／SentimentLedgerEntry
- packages/db：Prisma Client 存取層（ESM，因 Prisma 7 產出的 generated client 僅支援 ESM）
- apps/api 隨之改為 ESM 以相容 packages/db
- packages/shared：新增角色／記憶／情緒／關係共用型別，api 與 web 皆從此匯入
- prisma/seed.ts：建立測試使用者與元氣型測試角色，含完整關係帳本與記憶種子資料
- apps/api：新增 GET /characters
- scripts/smoke/B.mjs：驗證資料表齊全、API 讀出種子角色、關係與記憶可寫入讀出
- 保留 Prisma 官方隨 CLI 附的 agent skill 文件（.agents/skills 等），供後續群組查閱

npm run restart && npm run smoke -- B 皆通過（B-V），A 群組冒煙測試無回歸。

Prisma Client Setup

Generate and instantiate Prisma Client for Prisma's standard SQL provider workflow. For MongoDB, follow the provider-specific notes in references/mongodb.md instead of copying the SQL adapter example below.

1. Install dependencies

npm install prisma --save-dev
npm install @prisma/client

2. Add generator block

In prisma/schema.prisma:

generator client {
  provider = "prisma-client"
  output   = "../generated"
}

prisma-client requires an explicit output path and does not generate into node_modules by default.

3. Generate Prisma Client

npx prisma generate

Re-run prisma generate after every schema change to keep the client in sync.

4. Instantiate Prisma Client

import { PrismaClient } from '../generated/client'
import { PrismaPg } from '@prisma/adapter-pg'

const adapter = new PrismaPg({ connectionString: process.env.DATABASE_URL })
const prisma = new PrismaClient({ adapter })

If you change the generator output, update the import path to match. For the SQL provider workflow, replace PrismaPg with the adapter for your database.

5. Use a single instance

Each PrismaClient instance creates a connection pool. Reuse a single instance per app process to avoid exhausting database connections.
