Integrate reviewed first-tap guest disclosure repair

Preserve the exact reviewed guest touch commits and own-parent browser receipts. Retained final-source proof covers the small native eligibility repair; native thaw, installed recovery and release delivery remain separate.

+The custom Workloads guest row shares `Table`'s singleton non-activating native
+click marker for WebKit touch eligibility. Bind it only while a row action
