This update focuses on command handling and page permission behavior:
Fixed /backpack subcommand routing issues where commands like reload, migrate, or help could incorrectly open the backpack.
Improved command priority handling so player/admin subcommands are routed correctly.
Reworked page permissions to support dynamic numeric nodes: backpacks1653.pages.<number> now works with any integer.
Page permissions are now clamped safely to pages.max-pages.
Negative page values now resolve to 1 page.
backpacks1653.pages.* is optional and grants pages.max-pages.
Default setup now grants max pages without requiring the wildcard permission.

Some small bugfixes

Fixed major multi-page GUI issues (page switching, stuck state, nav/filler item protection).

Added fully configurable navigation row (previous-slot, next-slot, custom nav items).

Added /backpack priority override (default on) so Backpacks1653 wins command conflicts.

Improved migration detection for Minepacks/BackpackPlus folders and database files.

Added migration safety warning + explicit confirm flow for potential size-related item loss.

Expanded migration compatibility for modern BackpackPlus SQLite content format.

Improved Settings GUI localization usage and cleaned English defaults in config texts.

Added advanced update notification modes (major-only / medium-only / all updates).

Added built-in Spigot update checker (Resource 133312) with optional in-chat download link.

Added configurable admin update notifications on join (backpacks1653.update.notify).

Extended language auto-update: missing keys are now merged into all existing lang/*.yml files automatically.

Improved overall cross-platform readiness (Paper/Spigot/Folia)

Fixed the plugin not working on Folia and Spigot

Added message-format MINI_MESSAGE and LEGACY (Both)
