release: v1.0.6 optional local backup retention

Add optional KEEP_LOCAL_BACKUP environment variable to control local backup retention.

Default behavior remains unchanged: backup files are deleted locally after
successful upload, keeping deployments safe on Railway and other PaaS
platforms with ephemeral storage.

When KEEP_LOCAL_BACKUP=true is set, backups are preserved locally, which is
useful for CLI usage, local machines, VPS, or NAS workflows.

Documentation and CLI output were updated for clarity.
No breaking changes.
