feat: add json mode to cdnDelete function for suppressed console output

- Add optional 'json' mode parameter to cdnDelete() to suppress console output when set
- Implement thread-safe console output with mutex coordination during parallel deletion
- Add detailed progress messages (started, deleting, deleted/error, summary) with terminal styling
