Memorie Core V1.1.0 - Backpacks!!! [DISCONTINUED]

This update introduces the Backpack API — a fully data-driven persistent inventory system — alongside a rework of the water detection logic for the Dynamic Light engine.

• New module: Introduced a complete tag-based backpack system. Define storage size and display name with item tags alone — no scripting required.
• Persistent Inventory: Each backpack has its own independent inventory, saved and restored across sessions using Minecraft's Structure Manager.
• Automatic Management: The Core handles the backpack entity, inventory lock, lore generation, and player binding automatically.
• Tier Support: Different backpack sizes and types can be defined through tags, allowing full customization per item.
• Portal Safe: Backpack state is correctly preserved when the player travels through Nether and End portals.

• New feature: Items stored inside a Memorie Core backpack can now passively illuminate the player using the memorie:content_light_<1-15> tag.
• Passive emission: Light is applied as long as the item is inside any backpack in the player's inventory — the backpack does not need to be held.
• Non-conflicting: Uses a separate owner ID to avoid interference with the existing hand, armor, and dropped item light systems.

• Split detection logic: Water checking is now separated by entity type instead of using a single shared logic for all entities.
• Dropped items: Now use a low Y offset matching their actual position near the ground, preventing false water detection.
• Players and entities: Use a taller Y offset matching their body level for accurate in-water checks while wading or swimming.
