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 migrate diff

Compares database schemas and generates diffs (SQL or summary).

Command

prisma migrate diff [options]

What It Does

Compares two sources (--from-... and --to-...)
Sources can be:
- Empty (empty)
- Schema file (schema)
- Migrations directory (migrations)
- Database URL (url) or Configured Datasource (config-datasource)
Outputs the difference:
- Human-readable summary (default)
- SQL script (--script)

Options

Option	Description
`--script`	Render SQL script to stdout
`--exit-code`	Exit 2 if changes detected, 0 if empty, 1 if error
`--config`	Custom path to your Prisma config file

Sources (Must provide one `from` and one `to`)

--from-empty, --to-empty
--from-schema <path>, --to-schema <path>
--from-migrations <path>, --to-migrations <path>
--from-url <url>, --to-url <url>
--from-config-datasource, --to-config-datasource (uses prisma.config.ts)

Examples

Generate SQL for a schema change

Compare current production DB to your local schema:

prisma migrate diff \
  --from-url "$PROD_DB_URL" \
  --to-schema ./prisma/schema.prisma \
  --script

Review pending migrations

Compare database state to migrations directory:

prisma migrate diff \
  --from-config-datasource \
  --to-migrations ./prisma/migrations

Create baseline migration

Compare empty state to current schema:

prisma migrate diff \
  --from-empty \
  --to-schema ./prisma/schema.prisma \
  --script > prisma/migrations/0_init/migration.sql

Check for drift (CI)

Check if database matches schema:

prisma migrate diff \
  --from-config-datasource \
  --to-schema ./prisma/schema.prisma \
  --exit-code

Use Cases

Forward-generating migrations: Creating SQL without migrate dev.
Drift detection: Checking if DB is in sync.
Baselining: Creating initial migration from existing DB.
Debugging: Understanding what migrate dev would do.
