p77: 日历卡/浮动提示药丸化并修复面板遮挡快捷栏

- DrawCalendarCard 改半透明底+1px 描边+accent 发丝线，日历卡微缩(52→48)
- FloatingPrompt 新增 layoutWrapped/wrapText，锚定长文本逐字折行(不丢字、居中锚点、避让 HUD 带)
- 新增 HudLayout.panelRect，DrawPanel 用其几何；DialogOverlay.bottomMargin 24→72
  1280x720 下对话 rect 底 648、任务面板底 652，均 < hotbar 顶 660，不再压 3-8 号槽
- 新增 P77LayoutTests(4 尺寸不破版/不遮挡 + 真实长提示折行)
- 证据 LV_P43/P44/P67_SHOT + scripts/analyze-p77.py(verdict PASS) 落 docs/evidence/p77-*
- Desktop 361/361, Kernel 120/120, digest 953775FA...F7F6C 不变

+## P77 HUD 视觉精修收尾（日历卡 / 浮动提示药丸化 + 面板与快捷栏错开）

+  `SegmentBackdrop` + 顶部 1px accent + 四边 1px `Outline`；`calendarPadY` 由 8 收到 6，卡片高度
+  52→48（微缩），仍容下两行文字（`P43HudTests` 断言不变）。
+- 浮动提示（`Interaction.FloatingPrompt`）：新增 `layoutWrapped`/`wrapText`/`maxPromptWidth=360`，
+  锚定提示支持长文本**逐字折行**（不丢字、水平居中锚点、垂直钳制在顶/底 HUD 带之间）；渲染改
+  半透明深底 + 1px 描边 + 发丝高光，多行逐行描边绘制。原单行 `layout` 语义保留（既有测试不变）。
+- **遮挡修复**：新增 `HudLayout.panelRect`（底边恒抬到 hotbar 顶上方 8px），`Game.DrawPanel` 改用它
+  取几何；`DialogOverlay.bottomMargin` 24→72 预留底部快捷栏带。1280×720 下对话弹层 rect Y 由
+  558→510（底 648 < hotbar 顶 660），任务面板 rect=(16,536,380,116)（底 652 < 660），不再压
