Pull request overview

Adds a new “Towers of Hanoi” backup rotation strategy to the Backup core plugin, alongside integrity features (checksums + verification) and operational safeguards, extending BunkerWeb’s backup capabilities beyond simple FIFO retention.

Changes:

• Add BACKUP_SCHEDULE=hanoi (hourly job) with Towers of Hanoi rotation (24 files, ~85 days coverage).
• Add SHA-256 checksum generation for backups, checksum verification on restore, and a new bwcli plugin backup check command.
• Add a disk-space pre-flight check before dumping and adjust locking behavior to reduce lock hold time.
