UOW-010: Extend Engine Interface for Plugin Architecture

[andhijeannot]

Overview

Phase: 4 - Architecture
Priority: Medium
Estimated Effort: 10-12 hours

Problem Description

Current Engine interface is limited and doesn't support extensibility for custom template engines or plugin discovery/loading.

Acceptance Criteria

• Extended Engine interface supports plugin capabilities
• Plugin discovery and loading system implemented
• Plugin validation and security checks in place
• Documentation and examples for plugin development
• Backward compatibility with existing engines maintained

Files to Modify

• internal/engine/engine.go (extend interface)
• internal/plugin/plugin.go (new file)
• internal/plugin/validator.go (new file)
• examples/plugins/simple-engine/ (new example)

See roadmap/phase4-architecture/UOW-010-plugin-architecture.md for detailed implementation plan.
