// Canonical mapping from a canonical native-tool name to the
// `ProcessorKey` used for both metric rows and compressor labels.
//
// Two consumers of this map exist today:
//   - the compressor labels its emitted result with the same processor key
//     that the metrics row will carry.
//   - the metrics recorder classifies the row when the compressor passed
//     a result through.
// Importing from one source prevents the two paths from drifting.
