restore: bring back all custom UI enhancements from checkpoint

Restored from commit 52be710 (checkpoint before qwen oauth + todo roller):

Enhanced UI Features:
- SMART FIX button with AI code analysis
- APEX (Autonomous Programming EXecution) mode
- SHIELD (Auto-approval) mode
- MULTIX MODE multi-task pipeline interface
- Live streaming token counter
- Thinking indicator with bouncing dots animation

Components restored:
- packages/ui/src/components/chat/multi-task-chat.tsx
- packages/ui/src/components/instance/instance-shell2.tsx
- packages/ui/src/components/settings/OllamaCloudSettings.tsx
- packages/ui/src/components/settings/QwenCodeSettings.tsx
- packages/ui/src/stores/solo-store.ts
- packages/ui/src/stores/task-actions.ts
- packages/ui/src/stores/session-events.ts (autonomous mode)
- packages/server/src/integrations/ollama-cloud.ts
- packages/server/src/server/routes/ollama.ts
- packages/server/src/server/routes/qwen.ts

This ensures all custom features are preserved in source control.
