Clear and concise description of the problem

When using unbundle: true with multiple entries (e.g., via a glob), in watch mode context, Rollup/Rolldown rebuilds all entries when any source file changes. This makes development slower

Suggested solution

Optimize watch mode so that only the changed entry (and its dependencies) are rebuilt
