AI Summary: This issue proposes creating a Python script (`scripts/add_marker.py`) to streamline the process of adding new markers to map definition JSON files. The script will accept marker details via command-line arguments, automatically generate unique IDs, and update or create `data/markers/{map_id}.json`. It includes features like duplicate checking, category validation, and various output formatting options, all while using only standard Python libraries.
