Preserve structured WP-CLI recipe results

[chubes4]

Summary

Preserve successful structured WP-CLI output before temporary wrapper cleanup so recipe consumers receive the command result.

What changed

• Snapshot Playground response text while the temporary WP-CLI wrapper still exists.
• Add a recipe-level regression proving JSON output survives wrapper cleanup.
• Register the focused regression test as an npm script.

How to test

1. Run npm run test:wp-cli-recipe-result; expect Structured WP-CLI JSON remains in execution.result.json after wrapper cleanup..
2. Run npx tsx tests/wp-cli-temporary-script.test.ts; expect All 3200 temporary wrapper invocations remain isolated across concurrency levels..

Compatibility

Restores the existing WP-CLI recipe result contract without changing response schemas; exit codes, errors, and cleanup behavior remain intact.

Combined Lab verification update: run 50eadcfc-23c9-450a-929f-cb47f08f2a65 used integration commit 427cd1514bd157cc4fcf07cf6744acb1eb7d7d98 (#2054 + #2057). Structured WP-CLI output now survives cleanup and parses end to end; the import report, WordPress site plan, materialization receipt, and eight page provenance records are present.

The prior warning/truncation chain was fixed separately in #2057. The only remaining evidence gap is transformer_reference, tracked in #2058.
