fix(cli): handle EACCES gracefully in checkMode during permission scan

When the config directory lacks execute permission, stat on child files
(db, wal, shm) fails with EACCES instead of returning mode bits. Treat
EACCES like ENOENT (skip the file) since the directory permission check
will catch the root cause.
