Fix clippy collapsible_if in file_io3 cleanup

Browse Source 
dev-check runs clippy with -D warnings against the solutions, which
flagged the nested if let Some(dir_path) = ... { if dir_path.exists() ... }
in file_cleanup as collapsible. Combined into a single if-let with a
let-chain condition (edition = "2024", so this is available).

Verified locally: compiles under --edition 2024, clippy is silent,
and the binary still runs cleanly with file size 117 and no leftover
files.
