Add issue duplication detector agentic workflow with batch processing

[Copilot]

Create Issue Duplication Detection Workflow

• Create workflow file .github/workflows/issue-duplication-detector.md
• Configure workflow to trigger on schedule (every 5 minutes) for batch processing
• Set up read-only permissions (no write access)
• Configure GitHub tools for reading issues
• Configure bash tools with full access (all commands allowed)
• Configure safe-outputs for add-comment (max: 10 for batch mode)
• Write clear prompt for AI agent to detect duplicates
• Update to batch-process recent issues instead of per-event triggering
• Merge main branch and recompile workflow
• Compile workflow with gh aw compile issue-duplication-detector
• Verify compiled lock file was generated

Original prompt

Create an agentic workflow to detect issue duplication. If detected, comment on the issue that was duplicated and suggest next step. Do not modify issues and do not allow agent to have write permissions.

Custom agent used: create-agentic-workflow
Design agentic workflows using GitHub Agentic Workflows (gh-aw) extension with interactive guidance on triggers, tools, and security best practices.

Note that responding to every issue with an agentic workflows creates an unbounded $$$ spent that could be abused. If you can batch the analyzis in sets of 5 minutes windows, you get a guaranteed upper bound on $$$ and also natural batching of requests.

Changed to batch processing with a 5-minute scheduled window. The workflow now:

• Runs every 5 minutes via cron schedule instead of on every issue event
• Processes all issues updated in the last 10 minutes in a single batch
• Limits cost to at most 12 runs per hour with natural batching
• Increased max comment limit to 10 to handle multiple issues per batch
