DeleteDialog header now includes the total recursive size of
all paths to be deleted (formatted via format_size). For example:
'Delete 3 (1.2 MB) ?' instead of just 'Delete ?'.
Computed eagerly at construction via crate::ops::count_bytes so
render() does not block on filesystem traversal.
DeleteDialog (delete_dialog.rs):
- New field total_bytes: u64 (cached at construction)
- new() calls crate::ops::count_bytes(&paths) to populate it
- render() prepends '(N items)' to header and appends size when > 0
Tests (3 new in delete_dialog::tests):
- new_computes_total_bytes_for_directory (recursive dir sum)
- new_total_bytes_zero_for_missing_paths
- new_total_bytes_sums_multiple_paths
Total: 1271 passing (was 1268; +3 new).
