Bump bundled Agents API to v0.5.1

[chubes4]

Summary

• Bumps bundled wordpress/agents-api from 07300175de7004b3f5af75d16865a078a37203d4 to 59d1e6b473f22498e40e279130bbb4f9bcde3b73 (v0.5.1).
• Adds a Data Machine bootstrap guard for dual-loaded Agents API substrates: if AGENTS_API_LOADED is already defined, Data Machine skips the bundled require and logs a warning through datamachine_log when the active version differs from the bundled version.
• Adapts Data Machine smoke coverage and inspection output to the new Agents API v0.5.1 contracts.

Upstream Agents API changes included

• feat: Include post_id, post_type, published_url in agent ping payload (#383) #391 / 383c21e: suspendable workflow run model and branch-executor seam.
• feat: Add 'wp datamachine posts recent' CLI command (#384) #392 / 0cedec5: Action Scheduler branch executor for async parallel branches.
• docs: Add workspace CLI reference to agent skill (#381) #394 / 665c47e: serialized branch reconcile to avoid lost concurrent resume.
• fix: Comprehensive uninstall cleanup with multisite support (#382) #396 / 644a9e9: async branch payload offload out of Action Scheduler args and loud enqueue failure.
• Analytics tool: Google Analytics (GA4) integration #397 / 446733e: concurrent parallel branch fan-out and terminal-completion hook.
• feat: Add Google Analytics (GA4) and PageSpeed Insights integrations #400 / f58c436: branch concurrency gate counts pending plus in-progress work.
• Add CLI and REST layers for all analytics tools (GSC, Bing, GA4, PageSpeed) #401 / fa4fa1e: terminal resume keeps the AS concurrency ceiling open so fan-out drains itself.
• docs: Condense SKILL.md for agent operators (784 → 289 lines) #402 / 41c77fa: async-runner loopback derives scheme and port from the internal server.

Data Machine adaptations

• Updated standalone/package substrate layout assertions from legacy inc/... paths to current src/... vendor paths.
• Updated the workflow bridge smoke for upstream run-control, run-context, step-executor, completion-hook, and WP_Agent_Ability_Dispatcher dependencies.
• Kept Data Machine pending-action storage compatible with persisted preview_data rows while removing legacy preview_data from list/get inspection alias output; canonical output is now preview.
• Updated wp-ai-client boundary wording and vocabulary assertions for the current upstream source layout.
• Updated release-bundle smoke expectations for the intentional dual-load guard behavior.

Test evidence

• php -l data-machine.php && php -l inc/Engine/AI/Actions/PendingActionInspectionAbility.php && php -l tests/agents-api-standalone-skeleton-plan-smoke.php && php -l tests/agents-api-package-contract-smoke.php && php -l tests/agents-api-workflow-bridge-smoke.php && php -l tests/agents-api-wp-ai-client-vocabulary-smoke.php && php -l tests/release-bundled-agents-api-smoke.php: pass.
• composer lint: pass.
• Direct unique Agents API / pending-action smoke set: 21 scripts, 21 passed, 0 failed.
• Focused formerly-failing smokes: 5 scripts, 5 passed, 0 failed.
• composer test: not used as final verification because this machine's Homeboy Lab runner is blocked by known local infra/extension parity issues; direct smoke scripts were used as the verification path.
