Fix WinGet portable package runtime issues on Windows

[frankslin]

This PR fixes follow-up issues in the WinGet Windows release flow:

• build WinGet release binaries statically so the CLI does not depend on opencc.dll
• resolve Windows module paths to their final target paths so resource lookup works when launched
  through WinGet symlink aliases
• add schema headers to generated WinGet manifests to remove winget validate warnings

These fixes were identified while testing the actual WinGet installation flow on Windows, where
the package could install successfully but fail at runtime due to DLL loading and resource path
resolution issues.
