type declaration export of the entry module is saved to the runtime

[shulandmimi]

Steps to reproduce

1. install latest @farmfe/core @farmfe/cli

pnpm install @farmfe/core @farmfe/cli -D

2. create farm config

// farm.config.ts
import { defineConfig } from '@farmfe/core';

export default defineConfig({
    compilation: {
        presetEnv: false,
        input: {
            main: 'src/main.ts',
        },
    },
});

3. code

// src/main.ts
import { Person } from './dep';

export { Person };


// src/dep.ts
export interface Person {
  name: string;
}

4. build

npx farm build

What is expected?

should be cleared at compile time

import { Person } from './dep';

export { Person };

What is actually happening?

to the runtime

// dist/main.js

    ec2bf3a9: function (e, t, n, r) {
        'use strict';
        Object.defineProperty(t, '__esModule', { value: !0 }),
            Object.defineProperty(t, 'Person', {
                enumerable: !0,
                get: function () {
                    return o.Person;
                },
            });
        let o = n('ef454df0');
    },
    ef454df0: function (n, c, f, i) {},

Any additional comments?

After my simple review, it appears in dev and build

farm does not know it's type declaration. but it should be removed during tree shake. main.ts is entry so it won't be tree shaken
