• examples/dissmodel-configs/lucc_{continuous,discrete}.toml: registration config for dissmodel-platform, encoding the same coefficients as examples/run_*_via_executor.py
• Wire up python -m disslucc.executors.<name> run --toml ... --input ... (if name == "main": run_cli(...)) — didn't exist before
• Fix TOML table names ([[model.potential_data]]/[[model.allocation_data]], not potential/allocation) to match this package's required_parameters
• Lazy-import executors (PEP 562) to silence the RuntimeWarning python -m raised from disslucc/executors/init.py's eager imports
• LuccExecutorBase.save() now actually writes the output GeoTIFF (local path or s3:///MinIO, via dissmodel.io.raster.save_geotiff) instead of only hashing the backend's raw bytes in memory — record.output_path/ --output were silently ignored before this

Requires a dissmodel release past 0.6.3 (upstream fix: DisSModel/dissmodel#176) for the --toml merge to work locally; see docs/decisions.md for the full history and verification of each step.
