研究方向

The issue is about removing deleted files from the recently opened files list in Eclipse Theia. Start by locating the implementation of the recent files feature, which is likely in the 'editor' or 'core' package. The list is built from navigation history; you need to add a filter that checks file existence using the file service (e.g., `FileStat` or similar). Ensure that when the list is populated, files that no longer exist are excluded. The change is localized and straightforward.
