Fix smoke test: Extract engine to workspace, put SpringBoard in games/

Simplified structure following standard Spring engine layout:
- Extract engine to workspace root (./spring executable)
- SpringBoard-Core checkout is already at workspace root
- Symlink workspace as games/SpringBoard Core.sdd
- Engine finds the game via games/ folder

Structure:
workspace/ (SpringBoard-Core checkout)
├── scen_edit/, LuaUI/, modinfo.lua, etc.
├── spring (extracted engine)
├── games/
│   └── SpringBoard Core.sdd -> .. (symlink to workspace)
└── maps/

Much simpler - just download engine, put game archive in games/ folder.
