Create execution details from webhook responses

Editor assessment

The scope is accurate and the subject is a clean imperative statement of the feature: execution details records are now built from webhook responses. What is missing is any body, and a feature introducing a new kind of persisted record deserves a line on why execution details supersede raw logs and what shape they take, since those decisions affect every consumer of the data. The absence is not fatal because the subject is genuinely informative, but it leaves teaching value on the floor. Hygiene is good throughout. A competent feature message that stops one sentence short of good.
