*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary Implemented pseudoFS permission enforcement for VFS mutation operations: `unlink()`, `mkdir()`, and `rename()`. This change introduces parent-directory permission validation using `inode_checkdirperm()` before modifying pseudoFS inode topology. Unauthorized operations now correctly return -EACCES based on effective uid/gid and inode mode bits. The implementation preserves existing mountpoint filesystem behavior and correctly handles rename path-rewrite cases such as `mv file dir/`. ## Impact This extends pseudoFS permission enforcement by extending checks beyond open() into filesystem mutation paths. The update prevents unauthorized file removal, directory creation, and file renaming/moves including bypass scenarios where rename operations could previously modify filesystem state without proper parent-directory permission checks. ## Testing <img width="520" height="842" alt="image" src="https://github.com/user-attachments/assets/c7beb826-6dd8-4ce8-a499-83c634d04b51"; /> ostest also passed -- This is an automated message from the Apache Git Service.
