transpiled directory structure is flattened and malformed

[Vin-it]

Describe the bug

• I will reference this previous issue as it points out the issue I am pointing out here as well. Let's say we have this directory structure

➜  backend git:(master) ✗ tree -L 2 .
.
├── generated
│   └── some-api
├── integration-tests
│   └── one.ts
├── package-lock.json
├── package.json
├── src
│   ├── main.ts
│   ├── service-A
│   └── service-B
├── tsconfig-js.json
└── tsconfig.json

7 directories, 6 files

• I would like the structure to be analogous to the workspace (which is what I get when I run tsc -b)

➜  dist git:(master) ✗ tree -L 2 .
.
├── generated
│   └── some-api
├── integration-tests
│   ├── one.d.ts
│   └── one.js
├── src
│   ├── main.d.ts
│   ├── main.js
│   ├── service-A
│   └── service-B
└── tsconfig.tsbuildinfo

7 directories, 5 files

• But when I run swc . -d dist in this workspace, I get this structure (flattened one level and merged directories)

➜  dist git:(master) ✗ tree -L 2 .
.
├── main.js
├── main.js.map
├── one.js
├── one.js.map
├── service-A
│   ├── a.js
│   └── a.js.map
├── service-B
│   ├── b.js
│   └── b.js.map
└── some-api
    ├── api.js
    └── api.js.map

4 directories, 10 files

• I can get the correct result by running swc separately like this

swc src -d dist/src & swc generated -d dist/generated & swc integration-tests -d dist/integration-tests

Expected behavior

I would expect

• swc . -d dist
  to generate the following structure

➜  dist git:(master) ✗ tree -L 2 .
.
├── generated
│   └── some-api
├── integration-tests
│   ├── one.d.ts
│   └── one.js
├── src
│   ├── main.d.ts
│   ├── main.js
│   ├── service-A
│   └── service-B

7 directories, 5 files

Actual behavior

but I get

➜  dist git:(master) ✗ tree -L 2 .
.
├── main.js
├── main.js.map
├── one.js
├── one.js.map
├── service-A
│   ├── a.js
│   └── a.js.map
├── service-B
│   ├── b.js
│   └── b.js.map
└── some-api
    ├── api.js
    └── api.js.map

4 directories, 10 files
