fix: Fix corrupted view redirect, workspace cache flash and diff collapse (#1206)

1. Redirect to task input when task-detail view has no data or taskId
2. Optimistically update workspace cache on task create/open to prevent setup screen flash
3. Collapse unchanged lines in session diff viewer with 3-line margin
4. Replace direct ${{ steps.version.outputs.version }} interpolation in run: block with APP_VERSION env var
5. Fixed the sidebars per-folder plus button not pre-selecting the correct repo
