Automobility: Unofficial Port

Animals no longer occupy automobile seats.

• Prevented animals from boarding automatically or through normal mounting, including rear passenger seats, aquatic animals and bats.
• Animals already seated in an older save dismount safely on the next server tick.
• Players and non-animal mobs keep their existing boarding behavior.

Also includes the previously unpublished security, data-safety and position-sync repairs:

• Hardened vehicle input handling and attachment requests; clients cannot supply arbitrary physics, collision-damage or position values through the legacy packet.
• Added world-border and vanilla spawn-protection checks for harvester/plow changes.
• Preserved missing-addon component IDs and attachment inventory data across saves.
• Bounded datapack physics values, fixed raw automobile placement and stale menus.
• Repaired automobile/attachment rendering after server position corrections.
• Updated source and issue links to git.offchunk.com.

Beta: automated unit and dedicated-server animal-boarding tests are covered. Fresh manual driving, two-client observation and full modpack acceptance are not yet confirmed for this build. Back up worlds and match addon dependency ranges; older Pumps & Pistons/Roadworks candidates pinned to .33 require an addon update.
