[WIP] Update agentic workflows to use shared agentic workflow

[Copilot]

✅ Update Copilot Workflows to Use Shared Data Fetch - COMPLETE

Objective

Update copilot-* agentic workflows to use the shared copilot-pr-data-fetch.md component instead of custom steps, reducing duplication and improving maintainability.

✅ All Changes Completed

Workflows Updated (3 workflows)

• copilot-pr-nlp-analysis.md - Added shared import, removed duplicate fetch (-29 lines)
• copilot-pr-prompt-analysis.md - Added shared import, removed duplicate fetch, fixed typo (-31 lines)
• prompt-clustering-analysis.md - Added shared import, improved search method (-21 lines)

Workflows Verified (2 workflows)

• copilot-agent-analysis.md - Already correctly using shared component
• copilot-session-insights.md - Correctly doesn't need PR data (uses agent sessions)

📊 Impact Summary

Code Quality

• ✅ Eliminated 81 lines of duplicate code across 3 workflows
• ✅ Fixed syntax typo (\fi) in copilot-pr-prompt-analysis.md
• ✅ Improved search reliability (branch-based vs author-based)
• ✅ All custom workflow-specific steps preserved

Testing & Verification

• ✅ All 80 workflows compile successfully (0 errors, 12 expected warnings)
• ✅ All unit tests pass
• ✅ Shared component steps verified in compiled workflows
• ✅ No breaking changes to workflow functionality

Benefits

1. Single Source of Truth: All PR fetching now centralized in shared component
2. Better Maintainability: Changes to PR fetch logic only need updating in one place
3. More Reliable: Branch-based search (head:copilot/) more reliable than author search
4. More Flexible: 30-day data allows workflows to filter as needed
5. Cleaner Code: Net reduction of 37 lines across all files

Pull Request Overview

This PR successfully refactors three Copilot-related agentic workflows to use a shared PR data fetching component (shared/copilot-pr-data-fetch.md), eliminating code duplication and improving maintainability. The shared component fetches all Copilot PRs from the last 30 days using branch-based search (head:copilot/) instead of author-based search for improved reliability.

Key Changes

• Eliminated 81 lines of duplicate PR fetching code across three workflows
• Fixed syntax typo (\fi → \) in copilot-pr-prompt-analysis.md
• All workflows now use the centralized shared component for PR data fetching while preserving their workflow-specific custom steps
