Adds two new triggers that complement NeoForge's vanilla SaveToFile event:
PeriodicSaveService.java
- Dedicated single-thread daemon scheduler, started after server boot.
- Ticks every 'auto_save_interval_minutes' (config, default 10 min).
- On each tick: hops to main thread, snapshots every online synced
player via VanillaSync.snapshotAndQueueSave, async BG writes with full
P0 guard stack (pendingLogoutSaves + online=0 + bgLock tryLock).
- Set interval to 0 to disable.
VanillaSync.snapshotAndQueueSave(Player, String label)
- Extracted from onPlayerSaveToFile body; public entry point shared by
PeriodicSaveService, onPlayerChangeDimension, and the existing SaveToFile
event. Label flows into logs for traceability (SaveToFile / PERIODIC / DIMENSION).
VanillaSync.onPlayerChangeDimension
- New @SubscribeEvent on PlayerChangedDimensionEvent, gated by
'save_on_dimension_change' config (default false). Queues a full save
when a player teleports across dimensions, protecting against mid-
teleport crashes.
JdbcConfig
- Added AUTO_SAVE_INTERVAL_MINUTES (int, 0-1440, default 10)
- Added SAVE_ON_DIMENSION_CHANGE (bool, default false)
VanillaSync.onServerShutdown also stops PeriodicSaveService before the pool
close, same pattern as HeartbeatService.
