🤖 fix: remove workflow sidebar progress fraction

[ThomasK33]

Summary

Remove the compact completed/total fraction from workflow task-group rows in the left sidebar while preserving that fraction for best-of and variants task groups.

Background

Workflow rows already summarize progress in the secondary status line (for example, 1 running or 1 completed), so the extra right-aligned 0/1 indicator adds visual noise and truncates the workflow title sooner.

Implementation

• Gate the compact completed/total fraction behind non-workflow task groups in TaskGroupListItem.
• Let workflow headers use a single title column so the workflow name gets the reclaimed space.
• Add regression coverage that workflow groups omit 0/1 while best-of groups still render their fraction.

Validation

• bun test src/browser/components/ProjectSidebar/ProjectSidebar.test.tsx
• make static-check
• Storybook dogfood of Components/ProjectSidebar / Workflow Run Groups at desktop and narrow/mobile widths; verified workflow row text no longer contains 0/1 while the variants row still shows 0/2.

Risks

Low. This is a sidebar presentation-only change scoped to task-group headers. Best-of and variants rows keep their existing progress fraction, and workflow status text remains visible below the header.
