Tower of DLC v0.1.3 // DAI 2.1

- Rebuilt the Core Spire spiral around the actual city grid centerlines (+/-32).
- Added a two-step ground feeder so the Tower road now connects directly to street level with no air gap.
- Removed invalid Light Cycle faction/action metadata that caused four DAI validator errors.
- Reworked bike persistence so mounted-state logic no longer depends on player-side mount NBT.
- Added detached-cycle cleanup using the native entity passenger list.
- Fixed Cyan/Orange disc hit particles for Minecraft 26.2 command parsing.
- Fixed thrown Identity Disc item_display transformation serialization.
- Replaced title-screen texture icons with the stable MineTrigger-style item icon path.
- Added compatibility models for cached v0.1.1 Light Cycle frame IDs.
- Updated the daylight freeze gamerule to minecraft:advance_time for Minecraft 26.2.
