SFM-Flow

(0.5.22.alpha)

### [Added]

* Added a dedicated side-safe packet routing registry to handle network communications on the client. This protects server environments from loading client-only rendering classes and prevents dedicated server startup crashes.

* Added the Program Disk utility item, enabling players to clone entire flowchart layouts and variables between different Machine Inventory Managers.

* Added an interactive overwrite confirmation screen that queries the player before pasting configurations onto a Manager that already contains layout nodes.

* Added a shaped crafting recipe and creative tab registration for the Program Disk.

* Added a block ownership and access control system for Machine Inventory Managers. When placed, blocks are registered to the placer as the owner.

* Added an Access Settings button and permission modal to the Manager screen, enabling owners to toggle between Owner-only, Team-only (utilizing scoreboard teams), and Public access modes.

* Added localization keys and red floating warning prompts shown to unauthorized players attempting to access private Managers.

* Added a secondary-use override for server operators with level 2+ permissions, permitting administrative bypass of locked nodes.

### [Changed]

* Standardized all inventories list variables (Item, Fluid, Energy, Redstone, and Sign Updater) to resolve their block targets polymorphically.

* Re-routed all clientbound network packet processing securely through the client-only bootstrapping phase.

* Updated the Machine Inventory Manager block's interaction handler to support copying and pasting with the Program Disk.

* Block interaction is now restricted according to the assigned access level.

* Adjusted the vertical text coordinate offset of the sliding drawer label slightly to improve layout alignment.
