Tower of DLC v0.1.4 // DAI 2.1

- Added two registry-backed DAI architectural blocks: Cyan Grid Lamp and Orange Grid Lamp.
- Added authored always-on lighting across street grids, faction bases, hollow building floors/roofs, Core Spire interior levels, spiral Light Cycle roads, and the System Eye crown.
- Grid lamps are flush with traversal surfaces so bikes do not collide with lamp posts.
- Because DAI 2.1 native block registration does not currently expose luminance properties, each authored lamp is paired with an invisible Minecraft level-15 light cell above it.
- Added automatic v0.1.4 lighting migration for existing Tower of DLC saves.
- Fresh worlds now generate all lighting after city/tower geometry so roads and structures cannot overwrite it.
