Types haven't been bundled by microbundle

Microbundle ignores *.ts files if they contain only types. Example of the file: https://github.com/XaveScor/signal-components/blob/dff96fd7151db5aae7421059836794a7880c2649/src/types.ts.

Reproduction:

git clone https://github.com/XaveScor/signal-components
git checkout tags/v0.11.0
pnpm install
pnpm build

Expected Result:

types.d.ts is included in the ./dist directory.

Actual Result:

types.d.ts does not exist. Types are broken because we have ./types imports, but the file is missing.
