修复 / Fixes
- 输入框内余额标签固定被压成 44px 极简显示 → 按实际空间在完整/紧凑/极简三档自动切换 / The composer chip no longer always collapses to its 44px compact value; it switches between full, fit, and compact layouts by measured space
- 缩放 ≠ 100% 时误判空间不足 / Compact mode no longer mis-triggers at non-100% scale
- 悬浮停靠时被邻近面板遮挡 / Docked chips are no longer covered by neighbouring host panels
- 输入框内缩放上限 120%（悬浮/侧边仍可 125%）/ Scale slider capped at 120% in the composer row; floating and side docks keep 125%
45/45 tests pass. Verified on dsh 0.1.0-rc.7 (Windows + Edge).
