1.2.0

• Add a dry-run mode and actionable error messages to the UCP MCP tools, so an agent that gets a request wrong is told which field and why instead of receiving an opaque failure.
• Read the shipping address from where UCP sends it, so a checkout with separate shipping and billing addresses no longer ships to the billing one.
• Make checkout completion callable, and keep discount responses valid against the UCP schemas.
• Always send an absolute, openable order link in order.permalink_url — for guests it is the order's deep link, which works without logging in, and it is the same link the confirmation email uses.
• Refuse a guest order read in the protocol's own vocabulary: an agent asking for someone else's guest order is told the order was not found and that the permalink is how a guest order is read, rather than receiving an internal error.
• Report the code and severity of a failed agent request, and log the underlying exception, so a failure can be diagnosed from the shop's log.
• Require ucp-php-sdk 0.0.5 or newer, and accept every later 0.0.x release.
• Show the Agentic Commerce tab only on sales channels that can actually sell, and fix tab, template-selection and save-button inconsistencies across Shopware 6.5, 6.6 and 6.7.
• Mark parent listings that have variants correctly in the product feeds.
• Fix the installable ZIP shipping an administration that never loaded: the packaged plugin now contains a real, compiled admin bundle that works on Shopware 6.5, 6.6 and 6.7 alike, so the Agentic Commerce tab appears after a plain upload-and-install without rebuilding anything in the shop.
