Summary

• Embed the existing disktree icon in Windows executables using the Windows SDK resource compiler.
• Check the release executable for an embedded icon in Windows CI.
• Port the change from fix(windows): embed icon in executable tobi/disktree#37 to the cross-platform fork.

Testing

• Verified the ICO has four entries and the two ported files match upstream PR fix(windows): embed icon in executable tobi/disktree#37 byte for byte.
• git diff --cached --check passed.
• Rust/Cargo and rc.exe are unavailable locally; fork CI will run lint, tests, and the Windows release icon check.

Risks

• Windows builds require the Windows SDK resource compiler, already supplied with the MSVC SDK used by this project.
