- New cmd/acb-maps-loader reads all 200 map JSON files from maps/ directory
- Transforms map files into database schema format for maps table
- Supports INSERT with ON CONFLICT for idempotent updates
- Includes tests verifying all 200 maps can be parsed
- Updates Makefile with acb-maps-loader and load-maps targets
This addresses the plan-gap where maps/ had 200 maps but only 12 were in the database.
The index-builder generates maps/index.json from the database, so loading the full
map library enables complete map index generation.
