The Windows job failed at `flutter analyze` on the missing (gitignored,
generated) lib/src/build_info.g.dart — it never ran gen-build-info. But analyze
is platform-agnostic: the Linux job already statically analyzes windows_pty.dart
and everything else, and the flutter-build-windows release job catches
Windows-specific compile errors. Dropping it unblocks the job's real purpose —
running ConPTY under dart test — without needing build_info (the pty tests
import the pty libraries directly, not the build_info-bearing barrel).
