Your NameandClaude Sonnet 5 4e1f1cbf0f refactor(web): 提取共享的圆形多选勾选框组件,统一5处重复实现
创建群聊、消息多选、我的收藏多选、黑名单多选、转发选择器——这5个
地方各自手写了一份几乎一样的"圆形+选中变实心+里面check图标"勾选框
markup,样式上有细微且无意的差异(比如有的选中态多画了一圈边框、
用的灰色深浅不完全一致),上次只修了转发选择器一处,用户指出创建
群聊那里同样丑、而且问了"这种组件不该统一做吗"——確实该統一。

新增 `app/SelectionCheckbox.tsx`,把上次在转发选择器里验证过的
矢量勾选图标方案抽成共享组件,5处全部换成调用它。以后这个视觉样式
要再调整,改一个文件就够了,不会再出现"修好了一处,另外四处还是
老样子"的情况。

/**
* Shared circular multi-select indicator -- every list in this app that lets you pick multiple
* items (forward targets, message multi-select, create-group contact picker, favorites, blocklist)
* used to hand-copy this same circle-that-fills-with-a-checkmark markup into its own file, each
* with small, accidental class differences (a stray extra border in the selected state here, a
* slightly different gray there) -- fixing the same visual bug five separate times is exactly the
* failure mode a shared component exists to prevent.
*
* Draws the checkmark as a hand-drawn SVG path, not the Material Icons font glyph `Icon` uses
* everywhere else: the font's hinting isn't tuned for a ~13px glyph inside a 20px circle, so above
* 1x pixel density it renders visibly soft/asymmetric where a vector path stays crisp at any scale.
* A deliberate one-off exception to this app's usual `Icon`-for-everything convention, not a second
* icon system -- scoped to this one selection indicator.
