Fix script.txt format: MapName must reference .sdd directory

KEY DISCOVERY: MapName in script.txt must point to an actual .sdd directory
that contains mapinfo.lua, NOT just a name.

Changes:
1. CI: Create games/sb_test_map.sdd/ with mapinfo.lua and modinfo.lua
2. test-smoke.sh: Same - create .sdd structure before running
3. mapinfo.lua: NO mapfile field (triggers generation)
4. script.txt: MapName=sb_test_map 1.0 (matches .sdd directory)
5. MAPOPTIONS/MODOPTIONS: Pass generation parameters

How it works:
- Spring scans games/ directory
- Finds sb_test_map.sdd and loads it as a map
- mapinfo.lua has no mapfile field
- Spring tries to open empty mapfile, sets forcedQuit=1
- SpringBoard's Lua reads MAPOPTIONS and generates terrain
- Map generation happens via user's engine modifications

Tested with spring-headless --isolation and confirmed:
- .sdd directory is found ✓
- mapinfo.lua is read ✓
- Warning about empty mapfile appears ✓
- Loading continues through Feature Definitions ✓

Note: spring-headless still crashes during texture loading (separate issue),
but the script.txt format is now CORRECT for map generation.
