1) hint 텍스트에서 채널 정보 제거:
   "Slide up slightly ↑  (ch3 short)" → "Slide up slightly ↑"
   "Slide down slightly ↓  (ch0 short)" → "Slide down slightly ↓"
   사용자 피드백 — 채널 번호 표시 빼고 방향만.

2) edge 만 fail (CV·lrPass·rPeakOk 통과) 인 경우 GREEN 유지:
   기존: 방향 화살표면 무조건 nextPhase = VERTICAL → step indicator 3 → 1 회귀.
   변경: edgeOnlyFail 시 stayGreen=true → nextPhase = GREEN, step 3 유지.
   이유: edge 비대칭은 mm 단위 미세조정 — 전체 vertical 재시작 불필요.
   CV/lrPass 가 진짜 어긋난 경우는 기존대로 VERTICAL 회귀.
