Add Process Abstraction Layer to Core AI Module

Problem/Motivation

Implement a core process abstraction layer in the AI module to standardize handling of AI operations across different components (Agents, Automators, etc.).

Currently, different AI operations (Automators, Agents, Assistant) handle their processes independently, leading to:

• Duplicate code for process management
• Inconsistent status tracking
• Difficult process monitoring
• No standardized way to handle long-running operations

Proposed resolution

1. Core Interfaces
   • Process interface defining standard operations and states
   • Process storage interface for persistence
   • Process manager interface for lifecycle management
2. Storage Layer
   • Database schema for process tracking
   • Basic CRUD operations
   • Query capabilities for process listing
3. Event System
   • Process lifecycle events
   • Status change events
   • Error events
4. Base Implementation
   • Abstract process class
   • Default storage implementation
   • Process manager service

API changes

• New interfaces in Process namespace
• New events for process lifecycle

Data model changes

• New database table for process tracking.
