S-Loop v0.1.0-alpha.2

Fixes

• pi-server startup in packaged builds: Added nvm-windows paths, PATH scanning, and alternate drive installs to find_node_cmd()
• Missing extensions/ directory: Bumped @earendil-works/* from 0.80.3 to 0.80.6; fixed pack script to preserve extensions/ inside node_modules
• Error messages: Improved spawn failure diagnostics to show the attempted node path
