feat(agent-view): refactor to folder pattern and add Cursor model support

- Refactor agent-view.tsx from 1028 lines to ~215 lines
- Create agent-view/ folder with components/, hooks/, input-area/, shared/
- Extract hooks: useAgentScroll, useFileAttachments, useAgentShortcuts, useAgentSession
- Extract components: AgentHeader, ChatArea, MessageList, MessageBubble, ThinkingIndicator
- Extract input-area: AgentInputArea, FilePreview, QueueDisplay, InputControls
- Add AgentModelSelector with Claude and Cursor CLI model support
- Update /models/available to use ProviderFactory.getAllAvailableModels()
- Update /models/providers to include Cursor CLI status
