Path C: full U-2..U-5 re-flip with rustypipe fork (v0.1.0-AB vc=16)

Merges the kayos/path-c branch which moved straw's extractor from
NewPipeExtractor (Java) to strawcore (Rust + rustypipe via UniFFI).
See the C-1..C-6 commit chain for the per-phase breakdown; the final
state is v0.1.0-AB / vc=16:

- Zero org.schabi.newpipe imports in straw Kotlin
- Built against Sulkta-Coop/rustypipe v0.11.5-sulkta.2 (audit-hardened)
- iOS-first client order — pre-signed stream URLs, no sig deobf, no
  device attestation
- libstrawcore.so packs rustypipe + reqwest + tokio + rustls + rquickjs
  per ABI (~3-7MB each)
- APK 41.8MB (down from vc=15's 43.5MB, net of NPE removal)
- Verified end-to-end on emulator: search, video detail, inline player
  playback (NCS Spektrem), channel page (NCS 34.3M subscribers)
