Fiw Graves v1.1.0

Fixed

• Quick-collect (sneak + right-click) could silently delete items. Vanilla's own
  Inventory#add returns success as soon as it merges any portion of a stack into an
  already-partially-filled inventory — not only when the stack is fully consumed. The
  mod trusted that return value to decide whether to drop the leftover, so a partial
  merge (common with a nearly-full inventory) left the remainder undropped and it was
  then discarded when the grave slot was cleared. Quick-collect now checks the actual
  leftover count on the stack and drops it on the floor, every time.

Added

• Loot-backup safety net. Every grave's original contents are now snapshotted the
  moment it's created, independent of the live grave and of the existing anti-grief
  rollback history — it survives normal collection, so a bug anywhere in the
  pickup/expiry path (like the one above) still leaves a recoverable copy.
  • New config: lootBackupRetentionDays (default 7). Days to keep a backup;
    recommended presets are 1, 3, 7, or 14, but any value works. 0 disables
    the feature, -1 keeps every backup forever.
  • New command: /graves restore <player> [index] (operator-only) — restores a grave
    from its backup. Unlike /graves rollback, backups aren't consumed on restore and
    may still exist even if the player already collected the original grave, so check
    before using it to avoid duplicating loot.

Update immediately if you've had reports of players losing items on quick-collect —
this release fixes the root cause and gives you a recovery path (/graves restore) for
anything already lost, as far back as your lootBackupRetentionDays window reaches.
