Implement Explorer Subagent

[prosdev]

Description

Implement an explorer subagent that can discover patterns and explore code to provide insights for developers. This will help developers understand codebases better.

Acceptance Criteria

• Explorer can identify patterns in code
• Code exploration capabilities work across repositories
• Relationship mapping between components is implemented
• Similar code identification works correctly
• System integrates with the subagent coordinator

Technical Requirements

• Implement pattern discovery algorithms
• Create code exploration utilities
• Define clear interfaces for patterns and relationships
• Implement similarity measures for code
• Support for different exploration strategies
• Integration with the subagent coordinator
