Make node title non-editable in executions view

Editor assessment

The subject states the behavior precisely: the node title is no longer editable in the executions view. That is clear and names both the component and the surface. The fix type and editor scope are accurate. The body, however, is a single bug-emoji line that restates the subject with less precision, Fix node title non-editable in executions, contributing nothing; why the title was editable, or what interaction that broke, would have been the useful content. The PR reference is well formed. Style is otherwise clean. Clear subject, redundant body: mediocre in teaching value.
