fix(workflows): handle all os.Stat errors and suppress cover art logging

- Replace os.IsNotExist checks with full error handling in Hugo and
  Standalone workflow validation; catches permission errors, broken
  symlinks, and I/O failures early
- Pass nil to cli.PrintCover callback in main.go to suppress logging
  during Bubble Tea UI rendering and prevent stdout corruption of
  progress display
- Update tests for both workflow implementations
