Summary by cubic

Make tests cross-platform so they pass on Windows by normalizing paths and classpath handling. All 223 tests now pass on Windows 10.

• Bug Fixes
  • Replaced hardcoded POSIX paths with path.resolve, path.join, and path.normalize.
  • Used path.delimiter for Java classpath construction.
  • Updated test expectations in generator and version manager specs to compare resolved paths and storage locations.

^{Written for commit 8861681. Summary will update on new commits.}
