Summary

• Bootstrap Data Machine Code immediately when the plugin file is loaded after plugins_loaded has already fired.
• Covers WP Codebox/Playground activation flows where the plugin constants load but datamachine_code_bootstrap() would otherwise never run.
• Adds smoke coverage so github_issue_publish handler registration remains protected for late activation contexts.

Why

The wp-site-generator fanout fails in WP Codebox with required_handler_tool_unavailable because Data Machine Code is activated inside an already-loaded runtime. The plugin file loads, but the plugins_loaded callback is registered too late, so GitHub publish handlers never register on datamachine_tools.

Verification

• php tests/smoke-github-issue-publish-handler.php
• php -l data-machine-code.php && php -l tests/smoke-github-issue-publish-handler.php
