Summary of Changes

Hello @EmilyyyLiu, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求的核心目标是将 rc-overflow 包迁移到 @rc-component 命名空间下。这包括更新包的名称、其依赖项以及相关的构建配置，以使其与新的组织结构保持一致。此更改旨在标准化 @rc-component 生态系统内的包命名和依赖管理。

Highlights

• 包名迁移: 将包名从 rc-overflow 迁移到 @rc-component/overflow，这体现在 package.json、README.md 和 tsconfig.json 文件中。
• 依赖更新: 将 rc-util 和 rc-resize-observer 等依赖更新为它们在 @rc-component 命名空间下的对应版本，例如 rc-util 变为 @rc-component/util。
• 构建与发布脚本调整: 更新了 package.json 中的 prepublishOnly 脚本，改用 rc-np 进行发布流程，并移除了旧的 np 依赖。
• 移除 Vercel 配置: 删除了 now.json 文件，该文件可能包含了 Vercel 部署相关的配置。

Walkthrough

将包名从 rc-overflow 重命名为 @rc-component/overflow，统一替换代码与配置中的 rc-* 导入为对应的 @rc-component/* 包，更新 package.json（版本、依赖、发布脚本、React/TS 目标），并移除 now.json。无功能性逻辑变更。

Changes

Cohort / File(s)	变更摘要
包与配置变更 package.json, tsconfig.json, README.md, now.json	包名 rc-overflow → @rc-component/overflow，版本 1.4.1 → 1.0.0，发布脚本由 np → rc-np，升级 React/TypeScript 相关版本，移除 now.json 部署配置，tsconfig 别名同步更新。
核心源码导入更新 src/Item.tsx, src/Overflow.tsx, src/hooks/channelUpdate.ts, src/hooks/useEffectState.tsx	将依赖导入由 rc-resize-observer → @rc-component/resize-observer，rc-util 及其子路径 → @rc-component/util（包括 useLayoutEffect, raf, useEvent）。无其它逻辑或 API 变更。
示例与测试导入更新 examples/fill-width.tsx, tests/github.spec.tsx	示例与测试中相应替换导入源：rc-util/... → @rc-component/util/...，rc-resize-observer/... → @rc-component/resize-observer/...。
构建/脚本与依赖调整 package.json（依赖/开发依赖）	移除/替换若干包（如 @babel/runtime, rc-resize-observer, rc-util, np），新增/替换为 @rc-component/* 系列与 @rc-component/np，并更新测试/类型相关依赖版本（React 18 等）。

更改仅限包名与导入路径替换，控制流无变化，故不生成序列图。

变更为大量一致性替换与配置更新，逻辑未改动，审查重点为导入路径、package.json 与 tsconfig 的一致性。

兔子的庆贺诗

🐰 包名换新装，路径整齐跳两行，
依赖换了位置，代码依旧去忙忙；
版本归一笑开朗，编译跑通我欢畅。 🥕✨

Code Review

The pull request migrates the rc-overflow component to the @rc-component namespace. This involves updating the package name, dependencies, and import paths across multiple files. The changes appear to be straightforward namespace updates with version bumps. I have identified a potential issue with the version number in package.json and have raised a comment.
