Province entity and ProvinceService not found

[wayinone]

Describe the bug
In Vendure document, there are Province Entity and ProvinceService but not available in @vendure/core

To Reproduce
In a vendure project If you do

import { ProvinceService, Province } from '@vendure/core'

You will get error

"@vendure/core"' has no exported member named 'ProvinceService'.
"@vendure/core"' has no exported member named 'Province'.

Expected behavior
Both ProvinceService and Province are exported from @vendure/core

Actual behavior
You will get error

"@vendure/core"' has no exported member named 'ProvinceService'.
"@vendure/core"' has no exported member named 'Province'.

Environment (please complete the following information):

• @vendure/core version: 3.6.3
• Nodejs version: v24.10.0
• Database (mysql/postgres etc): postgres
• Operating System (Windows/macOS/Linux): macOS
• Package manager (npm/yarn/pnpm): npm

Workaround
If you would like to create a zone with province member: You can

• create Region with type province and point a parent in Country entity, and use script to add the province as a member into a Zone.

Additional context

• As I was trying to setup Tax Zone for US, which state (province) tax play important role on the setup. I stumpped into this issue.
• Currently, Zone (tax zone) can only be configured (via dashboard) with members from Country. However, in original Vendure setup, it should be able to configure with any thing in Region entity, or say, Province (Both Province and Country extends the Region entity)
• To clear the issue, it might be as easy as to add the following to the package

// in `packages/core/src/entity/index.ts`
export * from './region/province.entity';

and

// in packages/core/src/service/index.ts
export * from './services/province.service.ts'

• However, it would also be nice to have:
  • In dashboard -> Settings
    • Additional Province setting that allow user to create province through dashboard, and
    • In Zone setting, one can define member from Province (instead of just from Country)
  • In @vendure/create: user can populate Province with json file, similar to populate Country for initial dataset.
