feat: add GrabCraft blueprints, building helpers, and world state awareness

- Phase 1: Player position (querytarget @s) and testforblock tools
- Phase 2: GrabCraft scraper with LRU cache, 372-block Java-to-Bedrock
  mapping, search and auto-build blueprint tools with dryRun support
- Phase 3: Raise build limit to 5000 (MAX_BUILD_COMMANDS env), add
  progress notifications and build cancellation
- Phase 4: Geometric shape builders (sphere, cylinder, dome, pyramid,
  wall, box) using fill commands for efficiency
- Phase 5: Event buffer 100->1000 (EVENT_BUFFER_SIZE env), add
  getByTypes and getSince query methods
