/**
 * v0.8.4 §7 — `solosquad backup` subgroup.
 *
 * Owns lifecycle management of `~/.solosquad-backups/` — the same directory
 * already used by `migrate` to snapshot pre-migration state. Consolidates
 * three flags that previously lived in different commands:
 *
 *   - `migrate --list-backups`     → `backup list`
 *   - `migrate --delete-backup`    → `backup delete <id>`
 *   - `uninstall --also-purge-backups` → `backup purge`
 *
 * The migrate/uninstall flags still work in v0.8.4 (with deprecation
 * warnings) for a 1-minor compat window. Removed in v1.0.
