Use Agents API identity store for agent materialization

[chubes4]

Summary

• Add a Data Machine WP_Agent_Identity_Store adapter around the existing datamachine_agents table.
• Register the adapter through the canonical Agents API wp_agent_identity_store resolver.
• Route registered-agent reconciliation through wp_materialize_agent_identity() while preserving Data Machine owner access, directory, scaffold, and reconciliation hook side effects.
• Update the bundled Agents API lock to the commit containing the identity-store lifecycle.

Fixes #2593.
Requires Automattic/agents-api#319, now merged.

Testing

• php -l inc/Core/Identity/AgentIdentityStoreAdapter.php && php -l inc/Engine/Agents/AgentMaterializer.php && php -l inc/Core/Bootstrap/DependencyChecker.php && php -l inc/bootstrap.php
• ./vendor/bin/phpcs inc/Core/Identity/AgentIdentityStoreAdapter.php inc/Core/Bootstrap/DependencyChecker.php inc/Engine/Agents/AgentMaterializer.php inc/bootstrap.php tests/agent-registry-materializer-smoke.php
• php tests/agent-registry-materializer-smoke.php
• php tests/agents-api-persisted-agent-registry-smoke.php

composer test did not run tests: the Homeboy lab runner failed before PHPUnit because @automattic/wp-codebox-core was unavailable to the lab recipe builder.
