fix: add explicit outDir to rollup typescript plugin

The @rollup/plugin-typescript@12.3.0 update introduced stricter
validation requiring the TypeScript outDir to align with rollup
output paths.

This fix adds compilerOptions: { outDir: 'dist' } to the typescript
plugin configuration to satisfy the new validation.

Fixes build failures in PR #19 (development-dependencies group update)
