Release workflow fixes for the first Composer publication: isolated deploy keys for the PHP engine and Laravel split repositories, an explicit bootstrap mode before Packagist registration, and reproducible immutable tags on retries. Python and PHP publish from this new tag; existing public tags stay unchanged.
Complete the WooCommerce integration files referenced by the previous commit: native classic/block checkout, host-owned orders with durable payment attempts, HPOS support, the Docker demo, integration checks, plugin packaging and guides. The WordPress.org listing remains unsubmitted; this release does not submit it.
The local release gate runs Ruby, Python, PHP, .NET and ordered artifact checks in up to four concurrent lanes after shared builds, with separate logs, durations and a failing exit status if any lane fails. All existing checks are retained. The .NET runner builds and tests in Docker without a host SDK.
The custom element restores the selected swap asset when recovering an active payment attempt, so the existing swap instructions remain visible. Shared HTTP golden placeholders keep the JS, Ruby, Python and PHP fixtures in sync. All packages are versioned together at 0.4.5; the release gate rebuilds the Node/Express, Fastify, Laravel, FastAPI, Django, static HTML, Next.js and Rails demo assets against those packages. Live-wallet verification is reported separately in the release results; no manual payment is part of this release.
