Greptile Summary

This PR reverts the duplicate issue detection workflow from a Claude Code AI-powered approach back to the original wow-actions/potential-duplicates GitHub Action with text similarity matching (0.6 threshold). It also removes the Claude Code-powered duplicate PR detection workflow entirely.\n\n- Reverts .github/workflows/check_duplicate_issues.yml to use wow-actions/potential-duplicates@v1 with text-based similarity matching, removing the dependency on Anthropic API keys and Claude Code CLI\n- Deletes .github/workflows/check_duplicate_prs.yml, removing duplicate PR detection altogether\n- Eliminates CI dependency on LITELLM_VIRTUAL_KEY and LITELLM_BASE_URL secrets for duplicate detection workflows\n- The reverted issue checker file matches the original version from commit 37c014c80 exactly

Confidence Score: 4/5

• This PR is safe to merge — it reverts CI workflows to a previously working state with no impact on application code.
• Score reflects that this is a clean revert of CI workflow files only, with no application code changes. The reverted file matches the original version exactly. The only minor concern is the use of a tag (@v1) rather than a pinned commit SHA for the third-party action, but this is consistent with the repo's existing conventions for some actions.
• No files require special attention. Both changes are straightforward CI workflow modifications.

Important Files Changed

Filename	Overview
.github/workflows/check_duplicate_issues.yml	Reverts from Claude Code AI-powered duplicate issue detection back to the original wow-actions/potential-duplicates@v1 text similarity matching. The new file is identical to the original version from commit 37c014c. Adds edited event trigger alongside opened.
.github/workflows/check_duplicate_prs.yml	Deletes the Claude Code-powered duplicate PR detection workflow entirely. This removes a dependency on LITELLM_VIRTUAL_KEY and LITELLM_BASE_URL secrets and the @anthropic-ai/claude-code npm package for PR dedup.
