/**
 * Config backup/restore commands extracted from interactive-mode.
 *
 * `handleConfigBackupCommand` snapshots the reusable-file profiles and the
 * resource-relevant settings to a JSON bundle; `handleConfigRestoreCommand`
 * reads such a bundle back, confirming with the user before clobbering local
 * state. Both operate through a narrow `host` seam (settings manager + the
 * status/error/selector callbacks) so the file IO and validation live outside
 * the god file while interactive-mode keeps only thin delegating wrappers.
