v0.1.0-X (vc=12): revert to NewPipeExtractor for working playback

Phase U (rustypipe Rust extractor) rolled back. Symptom: black screen
on play, root cause: rustypipe 0.11.4's JS deobfuscator can't parse
current YouTube player.js (YT changed the obfuscation pattern, no
upstream rustypipe release since June 2025). Switching clients
(Web → TV → Android/Ios) didn't help — the deobfuscator init fires
universally.

Kept in place for the future:
- rust/strawcore/ Cargo workspace + UniFFI scaffolding
- build-host runtime install (rustup + 4 Android targets +
  cargo-ndk + NDK r27c)
- The U-2..U-5 commits in history (re-runnable when rustypipe is
  fixed or we fork it).

Restored from commit 9c4b3f831 (v0.1.0-T):
- NewPipe.init() in StrawApp.onCreate
- libs.newpipe.extractor + libs.squareup.okhttp deps
- NewPipeDownloader.kt + Thumbnails.kt
- ViewModels (Search/VideoDetail/Player/Channel/SubscriptionFeed) on
  NewPipeExtractor calls
- VideoDetailScreen Download dialog using NewPipe's StreamInfo

Future-direction memo: openclaw-workspace/memory/project_rustypipe_fork.md
— fork plan + revival path for the Rust extractor when we're ready
to maintain it.

Verified working in the Android emulator: dQw4w9WgXcQ plays, ExoPlayer
reports state=PLAYING(3), position advancing, video surface rendering.
