CHANGE phases in the GitHub Elements workflow. Closes current thread and opens next phase thread. This is a PHASE CHANGE operation, not just saving progress.USE THIS SKILL WHEN:- User says "transition to TEST" or "move to REVIEW"- User says "I'm done with DEV, start TEST" or "DEV complete"- User says "advance to next phase" or "close this phase"- User says "demote to DEV" (from TEST or REVIEW)- User says "tests pass, ready for review"- User says "merge this" (after REVIEW PASS)- User explicitly wants to END current phase and BEGIN nextDO NOT USE THIS SKILL WHEN:- User just wants to SEE status (use ghe-status)- User wants to START work on new issue (use ghe-claim)- User wants to SAVE progress but CONTINUE working (use ghe-checkpoint)- User wants reports (use ghe-report)- User is not ready to END current phaseIMPORTANT: This CLOSES current thread and OPENS next thread. Use ghe-checkpoint if you just want to save progress without changing phases.EXAMPLES:<example>Context: DEV work complete,
