Strip NewPipe: remove legacy :app + unused :desktopApp/:shared modules

Straw runs on the strawcore Rust pipeline and ships only :strawApp — it is not NewPipe and uses none of their app code. Removes the 12M org.schabi.newpipe :app module (the fork base) and the unused NewPipe-origin KMP :desktopApp/:shared scaffold. settings.gradle now includes only :strawApp; also drops the NewPipe SPDX header + the NewPipeExtractor includeBuild stub. This also kills the recurring config-time git failure from app/build.gradle.kts.
