    ci: check for duplicate pull requests (#837)
    
    ## Summary
    
    - instruct Copilot reviewers to search open pull requests for the same
    issue or change
    - ask reviewers to link any duplicate they find
    
    This helps surface duplicate work earlier in the review process.
    
    ## Testing
    
    Not run (documentation-only change, per instruction).
