When expanding a webhook delivery, a collapsible "Headers" section now appears above the payload. This surfaces metadata like content-type, signatures, and custom webhook identifiers that were previously hidden. For non-GitHub webhooks, the event title falls back to common header patterns (x-*-event, x-*-webhook-*) so deliveries are identifiable without expanding. Made-with: Cursor

Summary
When expanding a webhook delivery, a collapsible Headers section now appears above the payload. This surfaces HTTP metadata (content-type, signatures, custom webhook identifiers, etc.) that are currently stored in the event data but never displayed.

src/components/ListItem.tsx: extract headers from event data, render in collapsible sectionMotivation
smee.io is used beyond GitHub — any webhook producer can use it for debugging. HTTP headers often carry critical metadata (webhook type, signatures, trace IDs) that users currently cannot see without inspecting browser dev tools or running the CLI client. See #270 for details.
