Merge branch 'v0.13.0rc' into feat/react-query

Merged latest changes from v0.13.0rc into feat/react-query while preserving
React Query migration. Key merge decisions:

- Kept React Query hooks for data fetching (useRunningAgents, useStopFeature, etc.)
- Added backlog plan handling to running-agents-view stop functionality
- Imported both SkeletonPulse and Spinner for CLI status components
- Used Spinner for refresh buttons across all settings sections
- Preserved isBacklogPlan check in agent-output-modal TaskProgressPanel
- Added handleOpenInIntegratedTerminal to worktree actions while keeping React Query mutations
