refactor(mind-detail): B-1h soothe-toolbox 令牌化——29 处硬编码色收敛（零观感变化）

- 全全局映射、零局部调色板：呼吸圈薄荷/琥珀渐变落 §16 新登状态渐变阶
  （green-50/200/300、amber-200、sky-50、blue-600），免责声明落
  $status-warning-soft/-strong
- C-3 合规修复：transition: all 0.3s → background 0.3s ease
  （.breath-circle 各状态仅切换 background 渐变）
- 验证：等价回归唯一 DIFF 即上述 transition 行（有意变更），
  29 处色值编译产物逐字节相同
