Sulkta day-1: straw — KMP/Compose YouTube client fork

Initial Sulkta fork of NewPipe with a new :strawApp module that ships a
clean Compose-based Android APK at applicationId com.sulkta.straw.

What's here:
- :strawApp — thin Android application shell, MaterialTheme + StrawHome
  Composable. Lives alongside legacy :app so we don't break upstream.
- buildSrc — STRAW_APPLICATION_ID/VERSION constants alongside the existing
  NEWPIPE_APPLICATION_ID_OLD/NEW.
- docs/sulkta — RECON.md (NewPipe codebase breakdown) + DECISIONS.md
  (stack + scope decisions).

NewPipe's :shared KMP scaffold is at 892 LOC and renders nothing; this
fork picks up there and races ahead. Day-1 ships a hello APK; day-2 wires
NewPipeExtractor + Media3 player + SponsorBlock + Return YouTube Dislike.

GPL-3.0-or-later per upstream.
