Per plan §3.8, maps should be generated offline and stored in the map
library, not generated on-the-fly during matches. This commit adds
support for loading pre-generated maps from the database.
Changes:
- Add PreGeneratedMap type and WithMap option to MatchRunner
- Add loadPreGeneratedMap() to parse map JSON (walls, cores)
- Update worker to pass loaded map data to MatchRunner via WithMap
- Fallback to on-the-fly generation if map data is invalid
- Update acb-mapgen spawn radius to 25% for 2-player (aligns with match.go)
- Update test to verify cores are outside final zone radius
This enables the map library infrastructure (maps/, acb-mapgen, index
builder) to be used in production matches instead of being ignored.
