feat(pickaxe): implement Hooked_PickaxeItemGetDestroySpeed and Hooked_PickaxeItemCanDestroySpecial

- Add hook implementations for custom pickaxe tier support
- Hooked_PickaxeItemGetDestroySpeed: use CustomPickaxeRegistry destroy speed for configured pickaxes when mining effective blocks
- Hooked_PickaxeItemCanDestroySpecial: use CustomPickaxeRegistry effective blocks and harvest level (obsidian requires level 3)
- Add TryReadItemIdFromPickaxe and TryReadTileId helpers for reading item/tile IDs from native pointers
