feat(agent): Gradio-powered LangGraph agent chat with streaming, tool calls, file upload, conversation persistence
- Gradio 5.50.0 ChatInterface with type='messages' streaming - LangGraph create_react_agent with InMemorySaver checkpointer - 4 @tool functions: search_dashboards, get_health_summary, list_environments, get_task_status - Structured ChatMessage metadata (7 discriminator types: stream_token, tool_start/end/error, confirm_required, confirm_resolved, error) - HITL resume via second submit() with interrupt_before/Command - Dual-identity RBAC: service JWT + user JWT for tool calls - File upload (10 MB limit, pdfplumber/xlsx/JSON parser) - Conversation persistence via POST /api/agent/conversations/save - REST API: list, history, archive conversations; multi-tab gate; LLM config - LLM provider selection via Admin -> LLM Settings (assistant_planner_provider) - Svelte 5 AgentChatModel with stream event queue, dedup, stream_status watcher - MarkdownRenderer using svelte-markdown with semantic Tailwind tokens - ToolCallCard (3 states: executing/completed/failed) - ConversationList with search, date grouping, infinite scroll - ConnectionIndicator with Gradio health status - /agent route with two-column layout - Vite proxy /api/agent/gradio -> Gradio SSE - Fixed: not_() SQLAlchemy operator, route collision with _admin_routes - Fixed: conversation_id -> id normalization, .pyc cache staleness - Fixed: event.data array parsing (Gradio returns [jsonStr, null]) - Requirements pinned: gradio==5.50.0, pydantic>=2.7,<=2.12.3
