Update duplicate code workflow to target copilot SWE agent

[Copilot]

Overview

Updated the duplicate code detection workflow prompt to be specifically targeted at GitHub Copilot as an SWE agent. The changes transform the workflow from a conversational "you are an agent" style to a professional, task-oriented format that provides clear, actionable instructions suitable for automated remediation.

Key Changes

1. Professional Tone and Structure

Transformed the workflow from conversational to direct, imperative language:

Before:

# Duplicate Code Detection Agent

You are a code quality agent that analyzes commits to detect duplicated code patterns...

## Mission

When commits are pushed to the main branch, you must:
1. **Analyze Recent Commits**: Review the changes...

After:

# Duplicate Code Detection

Analyze code to identify duplicated patterns using Serena's semantic code analysis capabilities. Report significant findings that require refactoring.

## Task

Detect and report code duplication by:
1. **Analyzing Recent Commits**: Review changes in the latest commits
2. **Detecting Duplicated Code**: Identify similar or duplicated code patterns using semantic analysis
3. **Reporting Findings**: Create a detailed issue if significant duplication is detected (threshold: >10 lines or 3+ similar patterns)

2. Copilot Assignment

Added automatic assignment to @copilot in the issue template and guidelines:

**Assignee**: @copilot

## Summary
[Brief overview of duplication findings]

And in the operational guidelines:

### Issue Creation
- Assign issue to @copilot for automated remediation

This ensures created issues are automatically assigned to the copilot agent for potential automated fixes.

3. Enhanced Implementation Checklist

Improved the issue template checklist from generic "Next Steps" to a comprehensive "Implementation Checklist" with SWE-specific tasks:

## Implementation Checklist

- [ ] Review duplication findings
- [ ] Prioritize refactoring tasks
- [ ] Create refactoring plan
- [ ] Implement changes
- [ ] Update tests
- [ ] Verify no functionality broken

4. Refined Section Headers

Reorganized headers to be more action-oriented and professional:

• Mission → Task
• Current Context → Context
• Analysis Process → Analysis Workflow
• Detection Guidelines → Detection Scope
• Important Notes → Operational Guidelines
• Tool Usage Strategy → Tool Usage Sequence

5. SWE-Specific Language

Updated terminology throughout to target SWE agents:

• Changed "developers" to "SWE agents" where appropriate
• Updated final objective from "Remember: Your goal is to improve..." to professional "Objective: Improve code quality by identifying and reporting meaningful code duplication..."
• Added emphasis on enabling "automated or manual refactoring"

Testing

• ✅ Workflow compiles successfully
• ✅ All unit tests pass (59 workflows compile)
• ✅ Code review found no issues
• ✅ Generated .lock.yml contains updated prompt with @copilot assignment

Impact

This change makes the duplicate code detection workflow more suitable for GitHub Copilot as an automated SWE agent, with clear instructions for creating issues that can be automatically remediated by assigning them to @copilot. The professional tone and structured format align with how SWE agents process and act on instructions.

Original prompt

Update the duplicate code detection workflow prompt such that it generates an issue that will be assigned to github copilot agent. The tone and information should be reasonably and targeted at an SWE agent specifically, like copilot.
