Cancel Dr. Ralph

To cancel the Dr. Ralph diagnostic session:

1. Check if .claude/dr-ralph-loop.local.md exists using Bash: test -f .claude/dr-ralph-loop.local.md && echo "EXISTS" || echo "NOT_FOUND"

2. If NOT_FOUND: Say "No active Dr. Ralph session found."

3. If EXISTS:

   • Read .claude/dr-ralph-loop.local.md to get the current iteration number from the iteration: field
   • Note patient_name if present in the state file
   • Remove the file using Bash: rm .claude/dr-ralph-loop.local.md
   • Report: "Cancelled Dr. Ralph diagnostic session (was at iteration N)"
   • If patient notes exist, mention: "Patient notes were saved to [patient_file path]"
