Fix native asset packaging on Windows

[GT-610]

Summary

• install native assets emitted by Dart build hooks beside the Windows executable
• update flutter_pty to skip hook phases that do not build code assets

Problem

Windows builds generated the native asset manifest but did not copy its DLLs to the runner output directory. This caused RustLib.init() to fail to load sbm_ffi.dll before runApp, leaving a process running without an application window.

Testing

• flutter run -d windows
• verified the runner output contains sbm_ffi.dll, flutter_pty.dll, and sqlite3mc.dll
• verified the app reaches normal startup without the native-library load error
• flutter analyze lib/main.dart

Summary by CodeRabbit

• Improvements
  • Windows installations now include required native assets automatically, improving runtime reliability.
  • Updated the embedded terminal component to incorporate the latest fixes and enhancements.

Walkthrough

The packages/flutter_pty submodule reference moves to commit d8b917371f1fd1fb380f7b0f1148fa6c4cab67ca. Windows installation now copies native assets from native_assets/windows/ into the executable library directory as a Runtime component.
