/**
 * Canonical task and run status types for PD Runtime v2.
 *
 * Source: PD Runtime Protocol SPEC v1, Section 12
 * Source: Diagnostician v2 Detailed Design, Section 7
 *
 * MIGRATION NOTE:
 *   - openclaw-plugin's QueueStatus ('in_progress', 'completed', 'canceled')
 *     is the LEGACY status model. New code uses PDTaskStatus.
 *   - principles-core's EvolutionTaskRecord.status (free-form string)
 *     will be migrated to PDTaskStatus in M2.
 *   - The new status model introduces 'leased' and 'retry_wait' which
 *     do not exist in the legacy model.
