Address review feedback on react-component#731: the `this.reqs[uid]` and empty `parsedFile` branches fell through to `undefined`, breaking the `Promise<boolean>` contract even though `catch` already resolves `false`. Make every no-upload path resolve `false` so consumers can rely on a strict boolean, and assert the second overlapping retry resolves `false`. Co-Authored-By: Claude <noreply@anthropic.com>

src/interface.tsx:84-87允许customRequest返回void。src/AjaxUploader.tsx:301将该返回值直接写入this.reqs[uid]，因此void不会留下真值标记。两个并发的retry都能通过src/AjaxUploader.tsx:308-313的检查，第二次会再次调用post，并为同一个 UID 产生第二次自定义请求，而不是返回false。在请求跟踪边界将

In `@src/AjaxUploader.tsx`:
- Line 272: 为 fileInfoCache 建立清理生命周期：在 onSuccess
中按现有重试语义删除已完成文件的缓存；若失败结果也不可重试，则在对应失败回调中同步删除 fileInfoCache 的 uid
条目，否则为支持重试的缓存增加容量上限或显式清理机制，避免持续保留 origin 和 parsedFile。
- Line 305: Update the request registration flow around request and the
reqs[uid] entry so synchronous onSuccess/onError callbacks cannot be overwritten
by a later placeholder assignment: install the placeholder before invoking
request, retain the returned handle only if the entry still exists, and catch
request exceptions by removing the placeholder and returning false so retry
preserves its Promise<boolean> contract. Add coverage for a customRequest that
synchronously calls onError and returns void.

Per zombieJ's review on react-component#731: - Sync callback no longer leaves a dead in-flight marker. customRequest may synchronously call onError/onSuccess (which delete reqs[uid]) and return void; the placeholder must be installed before request(), and the handle is written back only when the entry still exists — otherwise the post-delete assignment wrote back {} and blocked every later retry. Add a regression test (customRequest that synchronously fails). - Clear fileInfoCache on success. A successful file is never retried (callers expose retry only for failed files), so its cached origin/parsedFile Blob references can be released instead of held until unmount. - Document the retry contract in README (en/zh): true/false meaning and that retry reuses the first upload's fileInfo (no beforeUpload/action/data re-run), so only previously uploaded files can be retried. 62 passed, tsc clean.

In `@README.md`:
- Line 103: Update the retry API documentation at README.md lines 103-103 and
README.zh-CN.md lines 103-103 to state that retry resolves false when no
reusable fileInfo cache exists, including after a successful upload clears the
cache; remove the claim that previously uploaded files can be retried.
In `@src/AjaxUploader.tsx`:
- Line 306: 调整 AjaxUploader 的 post 流程，在调用 onStart(origin) 之前先为 this.reqs[uid]
写入占位状态，防止回调同步调用 Upload.retry 时重复创建请求；若 onStart 抛出异常，删除对应占位符并重新抛出原异常，确保后续 abort
状态一致。

Background
下游 ant-design 正在为上传失败场景增加重试入口（ant-design/ant-design#59286）。antd 的
handleRetry在调用retry()之前会乐观地将文件状态置为uploading，但旧实现中retry()内部调用了processFile（重跑beforeUpload/action/data），存在以下问题：processFile中的beforeUpload等可能产生副作用（如图片压缩），retry 不应重复执行processFile的 reject 被.catch(() => {})静默吞掉，antd 设置的uploading状态无法回退，文件卡死参考 zombieJ 的评审意见，retry 应直接调用更底层的
post，而非重跑processFile。Solution
fileInfoCache，post()首次发起请求时按uid缓存入参（data/origin/action/parsedFile），retry()直接取出缓存复用，不再重跑beforeUpload/action/datareqs[uid] = {}占位符在onStart之前设置，防止同步双调 retry 重入；onStart包在 try/catch 中，异常时清理占位符并 re-throwreqs[uid] = handle || {}兜底：customRequest返回void时仍能挡住并发 retryfileInfoCache不主动清理：onSuccess是传输层成功不代表业务层成功（HTTP 200 业务码失败仍需 retry），onError/同步抛错后也需 retry，任何回调里删缓存都会误伤合法 retry；唯一安全清理点是组件卸载retry()返回void。缺少缓存时通过onError通知UploadRetrySkipError；已有活动请求时静默跳过Related Issue
Change Log
retry(file)方法，支持对已上传过的文件重试，复用首次上传参数，不重新执行beforeUpload/action/data
