Release version 0.12.1

• fix(pet): the desktop pet now reliably stays in the Running state across conversation switches, so the animation no longer gets pinned on Review after a previous turn finished or granted a permission.
• fix(pet): opening the pet window mid-conversation now immediately reflects the agent's current state instead of stalling on an outdated idle pose.
• feat(pet): changing the active pet in Appearance Settings instantly hot-swaps the sprite in the live pet window — no need to close and reopen for the new look to apply.
• tune(pet): the jumping animation has been retimed to follow a natural gravity arc, giving the hangtime a more believable, weighty feel.

发布版本 0.12.1

• 修复(桌宠)：切换会话时桌宠能稳定保持 Running 状态，不再因为此前轮次结束或授权操作而卡在 Review 动画上。
• 修复(桌宠)：在会话进行中打开桌宠窗口，会立即呈现当前真实状态，而不是停留在过时的 idle 姿势。
• 功能(桌宠)：在外观设置里切换激活的桌宠角色后，正在显示的桌宠窗口会即时热替换形象，不再需要关闭重开才能生效。
• 调整(桌宠)：跳跃动画按照重力曲线重新调速，滞空过程更贴近自然落体，体感更真实。
