[WardLu]

Summary

• remove AGENTS.md and CLAUDE.md from repository tracking
• ignore both files so local agent instructions do not enter future commits
• retain the files in local workspaces via index-only removal

Verification

• both local files still exist after git rm --cached
• staged public-repository gate passed
• git diff --cached --check passed

Boundary

• this removes the files from the current repository tree only
• existing Git history is not rewritten
