Data TransformsWebAssemblyMisconfiguration

Description

This rule triggers when Redpanda logs the error \n`invalid_argument: data transforms disabled - use \\`rpk cluster config set data_transforms_enabled true\\` to enable`. \nThe message indicates that WebAssembly-powered **Data Transforms** are turned off at\nthe cluster level, so any attempt to deploy or run transform functions fails.\n

Mitigation

1. **Enable the feature:** \n ```bash\n rpk cluster config set data_transforms_enabled true\n # restart all brokers for the change to take effect\n rpk redpanda stop\n rpk redpanda start\n ```\n2. Verify no emergency override (`emergency_disable_data_transforms`) is set.\n3. Make sure the cluster has enough memory for transforms and tune\n `data_transforms_per_core_memory_reservation` and\n `data_transforms_per_function_memory_limit` if you plan to run many or\n memory-heavy functions.\n
