Hi there, I am getting an issue about tsconfig resolution in module-tools. The document says if emitDecoratorMetadata is set to true in tsconfig.json, module-tools will invoke swc to transpile source code instead of directly bundling with esbuild.

But I noticed that if module-tools depends a tsconfig.json file which is extending from another tsconfig.json, module-tools will ignore the extended tsconfig.json (however dts generation will respect both), thus causes the output bundle being unexpected. As I dived into the source code of module-tools, I've noticed that it only parses the direct tsconfig.json file.

Is there any chance we can support parse extended tsconfig, since extending tsconfig.json can be useful (for example, in a monorepo project)? I tried to fix this in this PR: https://github.com/web-infra-dev/modern.js/pull/5427 , but since I'm new to this project, there may be mistakes for my implementation, so it would be appreciated if you can fix this or give me some advice XD

Reproduce Steps

• execute pnpm i
• execute pnpm build
• check dist output, _ts_metadata('design:*') is missing from output js (even though emitDecoratorMetadata is set in tsconfig.base.json)
• modify tsconfig.json, uncomment emitDecoratorMetadata and experimentalDecorators
• execute pnpm build
• check dist output, _ts_metadata('design:*') is present (work as expected)
