Workflow visualization with Temporal’s Timeline View

What this post added

Introduced the Timeline view to the Workflow Execution UI, providing a visual representation of workflow events over time. This view leverages Event Groups to display activities as time spans, indicating their outcome (color-coded) and parallelism. It also shows retry attempts for activities. Navigation and filtering are supported through scrolling, zooming, and event type filtering. The implementation uses the vis-timeline library and Svelte.
