ClayGrounds v0.2.8

- Fixed the startup-order race that could leave the player pinned forever while no world build was running.
- Added an idempotent bootstrap shared by Minecraft load and DAI worldgen startup.
- Worldgen now guarantees cg_world and loading bossbar state exist before writing generation scores.
- Added a startup watchdog that recovers the specific safe-platform-with-no-generator-state failure mode.
- Preserved the 374-step, approximately 2x TamaCrafti construction cadence.
- Preserved the lightweight 1 Hz center title, subtitle, bossbar and actionbar countdown.
- Completion now writes durable generation_requested/generation_complete storage flags.
- Terrain geometry, fountain, coordinates, encounters, class altars and CustomModelData IDs are unchanged.
