feat: Initial implementation of hermes-service with multi-user support

- Complete REST API with session management
- Dynamic user creation with isolated environments
- Multi-user isolation using /d/hermesai/users/{user_id}/.hermes structure
- Full command execution capabilities via Hermes CLI
- Health check and status endpoints
- Follows module development specifications

+# Hermes Service Web Application
+
+## Overview
+Hermes Service is a web application that provides API access to Hermes Agent functionality. It runs in the Hermes Agent environment and exposes CLI capabilities through REST/WebSocket APIs.
+
+## Features
+- Execute Hermes CLI commands via API
+- Manage multiple Hermes service instances
+- User and organization-based access control (using rbac module)
+- Real-time communication via WebSocket
+- Configuration management
+
+## Integration
+This module integrates with:
+- **rbac**: For user and permission management
+- **appbase**: For system parameter management  
+- **Hermes Agent**: Core functionality execution
+
+## Directory Structure
+- `hermes-service/`: Python package with core logic
+- `wwwroot/`: Frontend components (bricks-framework .ui files)
+- `models/`: Database table definitions
+- `json/`: CRUD operation definitions
+- `init/`: Initialization data
