Skip empty home environment values while preserving nonempty caller selections and platform precedence. Setup, doctor, and uninstall now use the same fallback home instead of writing relative paths in the current directory. Validation: focused home tests and the public setup/doctor/uninstall lifecycle under Node 24.18. Package verification and pack dry run are included in the integrated gate. Fixes #2325
