Fix bench component load before dependencies

[chubes4]

Summary

• Load/include the primary bench component immediately after ensuring it is active and before activating dependency plugins.
• Keep hook snapshots ahead of component/dependency includes so deferred plugins_loaded/init callbacks are still replayed.
• Update the bench smoke fixture so the dependency activates inside wordpress.bench and fails if it cannot see the primary component API.

Fixes #942.

Verification

• npm run build
• npx tsx scripts/bench-bootstrap-files-smoke.ts
• npx tsx scripts/recipe-bench-smoke.ts
• npm run check progressed through build, bench, recipe, and many smoke checks, but hit the local 10-minute shell timeout during recipe-interruption-artifacts-smoke with no assertion failure shown before timeout.
• npx tsx scripts/recipe-interruption-artifacts-smoke.ts also hit a local 5-minute shell timeout with no output.
