Add --no-print-skip option for suppressing SKIP log output

Introduce a new CLI flag --no-print-skip to hide SKIP status lines during sync/delete operations while preserving existing skip behavior and summary counters. Update help output, README, and AGENTS.md to document the new option.

+- `--no-print-skip` must suppress only `SKIP` log lines, without changing skip decisions or summary counters.
 - `--delete-dir` safety guard against dangerous paths (`/`, empty path, dot paths) must remain intact.

 ## Output
 
 The script prints status lines (`MKDIR`, `UPLOAD`, `DOWNLOAD`, `DELETE`, `RMDIR`, `SKIP`, `ERROR`) and a final summary with operation counters.
+
+Use `--no-print-skip` if you want to keep skipped-item accounting in the final summary but hide individual `SKIP` log lines during the run.
