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。

PostgreSQL Setup

Configure Prisma with PostgreSQL.

Prerequisites

PostgreSQL database (local or cloud)
Connection string

1. Schema Configuration

In prisma/schema.prisma:

datasource db {
  provider = "postgresql"
}

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

2. Config Configuration

In prisma.config.ts:

import { defineConfig, env } from 'prisma/config'

export default defineConfig({
  schema: 'prisma/schema.prisma',
  datasource: {
    url: env('DATABASE_URL'),
  },
})

3. Environment Variable

In .env:

DATABASE_URL="postgresql://user:password@localhost:5432/mydb?schema=public"

Connection String Format

postgresql://USER:PASSWORD@HOST:PORT/DATABASE?schema=SCHEMA

USER: Database user
PASSWORD: Password (URL encoded if special chars)
HOST: Hostname (localhost, IP, or domain)
PORT: Port (default 5432)
DATABASE: Database name
SCHEMA: Schema name (default public)

Driver Adapter

Use a driver adapter for the standard SQL workflow.

Install adapter and driver:
```
npm install @prisma/adapter-pg pg
```

Instantiate Prisma Client with the adapter:

import 'dotenv/config'
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 })

Common Issues

"Can't reach database server"

Check host and port
Check firewall settings
Ensure database is running

"Authentication failed"

Check user/password
Special characters in password must be URL-encoded

"Schema does not exist"

Ensure ?schema=public (or your schema) is in the URL
