* fix(canvas): 分镜脚本节点文字溢出与视频模型下拉异常 #84

- CompactInput 补齐 overflow-y-auto/whitespace-pre-wrap/break-words，长文本不再横向溢出撑开列宽
- filterModelsByCapability 增加 modelCosts[].protocol 协议层回退，未显式配置 capability 时通过协议识别能力
- isVideoModelName 扩展 pika/runway/gen-3/hunyuan-video 等主流视频模型名关键字
- ModelPicker.options 保留当前选中 value，避免过滤后 options 为空触发跳转设置页

* fix(canvas): 模型过滤协议反向排除 + 分镜脚本节点模型选择提示 #84

- filterModelsByCapability 协议层提升至最高优先级，协议明确属于其他能力时直接排除，
  防止 video/image/audio 协议的模型被误标为 text 后混入文本下拉
- isVideoModelName 补充 cogvideo/mochi/latte/stable-video/svd/animatediff/ltx-video/minimax-video/abab-video 等关键字
- isImageModelName 补充 nano-banana/ideogram/recraft/playground/leonardo 等关键字
- 分镜脚本节点 ModelPicker 包裹 Tooltip，提示"脚本生成仅支持文本模型"

* fix(canvas): 节点标题截断修复 — flex min-width 约束 + 宽度边界 + hover tooltip

- NodeExternalHeader: 容器增加 max-w-full 双重约束，窄节点时不越界，宽节点时上限 240px
- NodeExternalHeader: 标题 span 增加 min-w-0，解决 flex min-width:auto 导致 truncate 失效
- 所有节点标题（绘图/技能/角色参考/音频/分镜脚本）增加 title 属性，hover 显示完整标题
- AudioNodeContent: 标题 span 增加 min-w-0，修复 flex 子项截断

* fix(canvas): 节点顶部标题真正截断 — JS 计算 maxWidth + overflow-hidden + flex-1

- NodeExternalHeader 容器: 移除 Tailwind 级联冲突的 max-w-[240px]/max-w-full，
  改用 JS 计算 Math.min(240, node.width) 作为 inline style maxWidth，
  从根本上解决两个 max-width 声明的优先级不确定问题
- 容器增加 overflow-hidden 作为第二道防线
- 内部 text/input/button 元素改用 flex-1 + min-w-0 替代固定 max-w-[Npx]，
  让 flex 子项自动填充可用空间，文本在剩余空间内截断

* fix(canvas): 节点标题缩放溢出 — 考虑 canvas zoom scale

- maxHeaderWidth 改为 Math.min(240, node.width * scale)，
  因为 header 的视觉宽度 = maxHeaderWidth（inverseScale 与 canvas scale 抵消），
  而节点的视觉宽度 = node.width * scale，两者必须比较同一维度
- 修复 zoom 缩小时（scale < 1）header 视觉宽度超过节点视觉宽度的溢出问题
