feat: add AI chat panel with Vercel AI SDK integration

Browse Source

Add a comprehensive AI assistant feature to netcatty, enabling AI-powered
terminal automation and multi-host orchestration.

Core features:
- AI chat side panel (Zed-style) with agent selector, session history,
  conversation export (Markdown/JSON/TXT), and streaming responses
- Catty Agent: built-in terminal assistant with 9 tools (terminal exec,
  SFTP read/write, multi-host orchestration) using zod schemas
- BYOK provider support: OpenAI, Anthropic, Google, Ollama, OpenRouter,
  and custom OpenAI-compatible endpoints
- Three-tier permission model: Observer / Confirm / Autonomous
- Command safety: blocklist patterns, doom loop detection, abort support
- External agent support: ACP protocol (JSON-RPC over stdio) for
  Claude Agent, Codex CLI, Gemini CLI, and custom agents

Tech stack:
- Vercel AI SDK (ai, @ai-sdk/openai, @ai-sdk/anthropic, @ai-sdk/google)
  with streamText + fullStream for streaming tool-call loops
- AI Elements: adapted conversation (use-stick-to-bottom), message
  (streamdown markdown), prompt-input (InputGroup) components
- Custom bridge fetch adapter routing all API calls through Electron
  main process IPC to avoid CORS
- zod for tool parameter schemas

UI components:
- AIChatSidePanel, AgentSelector, ChatInput, ChatMessageList
- PermissionDialog, ExecutionPlan, ConversationExport
- AI Elements: conversation, message, tool-call, prompt-input
- New UI primitives: InputGroup, Spinner
- Settings AI tab for BYOK configuration and safety settings
