Detection for missing use client directive

In some projects we didn't catch 'use client' directives missing, it would be great to have a code infra step that could check about this.

Potential ways we can do this:
- updated eslint plugin: needs to investigate impact on next.js perf
- Look into rollup plugin that can detect all react usage from non-client entrypoints and their fully resolved module graphs
- Do we have any code in BUI where a RSC makes sense?
