v1.6.2

Fixed

• A failed or empty storage backup can no longer report success. After building the archive the agent now checks its size; a < 100 B (or unreadable) file is treated as "nothing to back up" — it logs a warning, removes the stub file and skips the upload instead of silently reporting a successful run. The heartbeat success timestamp is likewise stamped only after a real upload completes, so a creation failure or an empty source can no longer leave a green heartbeat behind a backup that never actually shipped.

Changed

• Backup commands fail cleanly. Archive-creation errors now exit 1 with a readable message via the shared backup flow instead of surfacing an uncaught stack trace.
• CLI output overhauled. notifier:check, the backup commands, notifier:heartbeat and notifier:install now share one pass/warn/fail report vocabulary with a tri-state RESULT summary; notifier:install masks the backup code/password in its recap (presence and length only, never plaintext); a non-writable storage path prints an actionable chown/chmod hint; and logo/badge/ANSI decoration is suppressed when the output is not a TTY, so cron and redirected logs stay clean.
