v0.3.0

Pairs with minecraft-bedrock-mcp-server
v0.3.0 — install both together.

Added

• mc_structure_create_from_blocks command handler — builds a saved structure from a
  run-length-encoded block grid. It calls createEmpty (world-saved by default) and then
  setBlockPermutation for each non-void cell inside a runJob that yields under the
  script watchdog, so the result is immediately placeable and persists across reloads.

Removed

• mc_server_reload_world command handler. The structure-upload feature it supported now
  builds structures in the world directly and needs no /reload all.
