fix(windows): add fallback paths for hoisted optional dependencies

- Windows binary not found due to npm hoisting optional dependencies
- Add multiple search paths: nested, hoisted, and global locations
- Improved error messages showing all searched paths
- Fixes Windows installation where binary wasn't found

Closes issue where 'cm' command failed on Windows with platform binary not found error
