Description

Ensure the platform wrapper scripts select the correct compiled binary on Windows. The executable should include the .exe suffix so that global installation works with npx and bunx.

Acceptance Criteria

• [x] cli.cjs resolves backlog.exe when process.platform is win32.
• [x] cli-download.cjs downloads backlog.exe on Windows.
• [x] Unit tests cover these behaviors.

Implementation Notes

The Windows .exe extension handling has been fully implemented:

1. getBinaryName.cjs (shared utility):

   • Correctly detects Windows platform using process.platform === "win32"
   • Appends .exe extension to binary names on Windows
   • Maps Node.js platform names to Bun target names appropriately

2. cli.cjs (wrapper script):

   • Uses getBinaryName() to resolve the correct binary name including .exe on Windows
   • Spawns the binary with windowsHide: true option for better Windows compatibility

3. cli-download.cjs (download script):

   • Uses getBinaryName() to download the correct binary with .exe extension on Windows
   • Skips chmod operation on Windows (only sets executable permissions on Unix)
   • Also uses windowsHide: true when spawning the downloaded binary

4. Test Coverage:

   • getBinaryName.test.ts specifically tests that .exe is appended on Windows platform
   • build.test.ts handles Windows executable naming in build tests
   • All tests pass successfully
