[Bug] .d.ts missing for some entries

[unional]

Describe the bug

A clear and concise description of what the bug is.

Steps to reproduce the behavior

When doing build, even though the dts is building the .d.ts files, they are missing in the /dist folder.

DTS Build start
DTS Build start
DTS Build start
DTS ⚡️ Build success in 1454ms
DTS dist/preview.d.ts 359.00 B
DTS ⚡️ Build success in 1499ms
DTS dist/vitest-plugin.d.ts 1.34 KB
DTS ⚡️ Build success in 2089ms
DTS dist/vitest-setup.d.ts 403.00 B
DTS dist/index.d.ts        703.00 B
DTS dist/matcher.d.ts      186.00 B

The problem is that the commonConfig set clean: true,
which causes the last DTS build wipe out the previous artifacts.

Setting it to clean: false would fix the issue.

Maybe this is a bug should be fixed in tsup?
