refactor(chat): deduplicate streaming code, add multi-conv, and XSS protection
- Add ChatEngine for deduplicated chat logic (handlers_chat/shell_chat) - Add SendWithToolsStream for real-time streaming responses - Add /help, /plan, /export, /model commands in Studio - Fix XSS: sanitize HTML after markdown rendering - Add ConversationStoreMulti for multi-conversation support - Add Anthropic headers (x-api-key, anthropic-version) - Add fallback logging when provider switch occurs - Add API handler tests (handlers_test.go) - Polish Studio: max-height 200px, word-break on tool args - Update CLI version to show full info (version, go, platform) 🤖 Generated with Crush Assisted-by: MiniMax-M2.5 via Crush <crush@charm.land>
