Expose pipeline outcome classes

[chubes4]

Summary

• Adds additive RunMetrics outcome class/count fields for empty-query, provider, hydration, AI empty-packet, missing handler-packet, source-rejected, and item-deferred outcomes while preserving existing job statuses.
• Records routed step failure reasons so empty_data_packet_returned and handler_requiring_step_missing_handler_packets remain machine-readable in metrics.
• Shows outcome classes in wp datamachine jobs metrics table output and expands smoke coverage for the generic outcome contract.

Tests

• php tests/job-outcome-metrics-smoke.php
• php tests/run-metrics-smoke.php
• php tests/transition-fanout-policy-smoke.php
• php tests/ai-error-status-propagation-smoke.php
• php tests/fetch-item-dispositions-smoke.php
• php -l inc/Core/RunMetrics.php
• php -l inc/Abilities/Engine/ExecuteStepAbility.php

• git diff --check

Caveat

• composer test reached WP Codebox test execution, then failed with an unclassified exit before structured counts were reported. The generated .pg-test-result.txt referenced in the output was not present afterward, so there was no additional failure detail to inspect locally.

Fixes #2172.
