Bedrock Allow Deny Border

Fixed

• Border blocks now block the entire (x, z) column at every Y (world bottom to top): entities that are not allowed to pass can no longer cross the wall by jumping over it, flying/elytra above it, or tunnelling underneath it. Implemented as a virtual full-height column barrier (per-world border column index + collision-stream injection), keeping all privilege rules intact.
• In "Block all entities" mode, high-flying projectiles (arrows, spectral arrows, tridents, ender pearls, snowballs/eggs, fireballs, shulker bullets, ...) are stopped at the border column as well; projectiles fired by privileged players still pass.
• Per-block NBT whitelist now applies to the whole column the block belongs to (any border of that column can open it).

Notes

• Version scheme changed to {mod_version}+{mc_version} from this release on.
