feat: Refactor services architecture and update project structure

- Remove Docker-based microservices (docker-compose.yml, Makefile, Dockerfiles)
- Update start-dev.sh to use backend.app:app entry point
- Add shared schema and client modules for service communication
- Add team coordination modules (messenger, registry, task_delegator, coordinator)
- Add evaluation hooks and skill adaptation hooks
- Add skill template and gateway server
- Update frontend WebSocket URL configuration
- Add explain components for insider and technical analysis

+# EvoTraders Services Architecture
+
+This document describes the modular service architecture for EvoTraders.
+
+## Architecture
+
+EvoTraders uses a **modular single-process architecture** with services as Python modules:
+
+```
+backend/
+├── app.py              # FastAPI entry point (port 8000)
+├── main.py             # CLI trading system entry point
+├── api/                # REST API routes
+│   ├── agents.py       # Agent management
+│   ├── guard.py       # Tool guard
+│   ├── runtime.py      # Runtime management
+│   └── workspaces.py   # Workspace management
+├── agents/             # Multi-agent system
+│   ├── base/          # Base agent classes
+│   ├── team/          # Team coordination
+│   └── skills/        # Agent skills
+├── core/               # Pipeline & scheduler
+├── services/           # Core services
+│   ├── gateway.py     # WebSocket gateway
+│   ├── market.py      # Market data service
+│   └── storage.py     # Storage service
+└── services/          # Modular services (optional)
+    ├── trading/       # Trading module
+    ├── news/          # News module
+    └── agents/        # Agents module
+```
+
+## Entry Points
+
+| Entry Point | Port | Purpose |
+|------------|------|---------|
+| `backend/app.py` | 8000 | FastAPI REST API |
+| `backend/main.py` | CLI | Trading system (live/backtest) |
+
+## Running
+
+```bash
+# Development mode (FastAPI only)
+./start-dev.sh
+
+# Or manually
+python -m uvicorn backend.app:app --port 8000 --reload
+
+# Trading system (CLI)
+evotraders live --mock
+evotraders backtest --start 2025-11-01 --end 2025-12-01
+```
+
+## Service Modules
+
+| Module | Description |
+|--------|-------------|
+| `gateway.py` | WebSocket gateway for frontend communication |
+| `market.py` | Market data fetching (prices, news, financials) |
+| `storage.py` | Dashboard state and trade history persistence |
+
+## Module Dependencies
