Memory Database Backup

Runs a backup of the configured production database.

mirror backup

This command:

• Archives a consistent snapshot of the database, one memory.db in WAL mode, readable only by its owner
• Removes backups older than 30 days
• Also runs automatically at session end through the SessionEnd hook

The backup succeeded only when the command exits 0 and prints a Backup created: line. Then tell the user: "Memory database backed up." and show that line.

If the command exits non-zero, or prints a line starting with backup: no archive was written:, the backup failed. Tell the user so, quote that line, and never say the database was backed up.
