Restore fails fast on first error; --skip-errors is now global

restore aborts on the first per-file failure by default, surfacing
the file path and the underlying error and suggesting --skip-errors
to continue past failures.

--skip-errors moved from a 'snapshot create' subcommand flag to a
top-level persistent flag on the root command. It applies to both
snapshot create and restore. Old 'vaultik snapshot create --skip-
errors' still works because persistent flags are inherited.
