LazyRoad

This commits a massive architectural overhaul to bring the LazyRoad engine up to modern (1.13+) ecosystem standards natively targeting Java 21, resolving block registration bounds, and expanding generation logic.

Key Changes:

• JSON Templates: Eliminated the broken legacy .ser binary files. Engine now extracts and parses natively editable .json layouts for 10 roads and 6 pillars. Uses modern string namespaces (e.g. minecraft:stone) ensuring forward compatibility with brand new Minecraft blocks without requiring SDK recompiles.
• Directional Block Support: Modern orientable blocks (stairs, fences, hanging lanterns) natively calculate structural rotation based on dynamically changing road paths (North/South/East/West).
• Tunnel Engine Refactor (/lt): Sub-engine now generates a volumetric bounding box that precisely carves and clears blocks ahead of the player rather than just bypassing placement. Added a /lr drops toggle to toggle dropping excavated blocks as actual items.
• Tunnel Render Fix: Injected synthetic BlockDamageEvents to force-trigger adjacent engine updates specifically fixing block state masking problems with anti-xray plugins like Orebfuscator.
• Bridge Engine Fix (/lb): Properly mapped flag overrides in the command router and shaved off dead "invisible" block data at the bottom of pillar arrays allowing suspension cables to correctly anchor down to the physical terrain.
• Infinite Undo Restoration (/lr undo): Engine now scales using dynamic ArrayLists instead of hard-capped buffer sizes. Restructured the timeline array to restore chronologically backward (LIFO), perfectly reverting structurally complex tasks like Tunneling without leaving displaced air cavities.
• Updated Pom.yml SDK targeting and rewrote the README.md to accurately document JSON parameters and modern command syntax.
