UpdateMeta only cleared the old path from cache, leaving a stale nil entry at the new path if it had been accessed before. Now also clears the new path's cache entry so changes take effect immediately. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

问题
修改 meta 的路径后，新路径不会立即生效。
根因：
UpdateMeta更新路径时，只清除了旧路径的缓存（old.Path），但未清除新路径可能已存在的缓存。如果新路径曾被访问过（缓存了
nil，即"不存在"），该负缓存不会被清除，导致访问新路径时仍命中缓存返回
MetaNotFound，最长持续 1 小时（缓存 TTL）。修复
在
UpdateMeta中同时清除新路径的缓存，确保下次访问时从数据库重新加载。变更
