1.0.0

MIT licensing update: the original mod code and assets, including earlier uploads of this version, are now offered under MIT. The refreshed JAR includes the license text and updated metadata; compiled implementation and version number are unchanged.

• Sealed orbs are now single-use in both survival and creative mode.
• Consume the original orb before executing its command so rewards placed into the vacated slot are not overwritten or deleted.
• Prevent vanilla creative-mode use from restoring the consumed orb.
• Preserve the default state until a successful save writes the Modified marker; sealed data remains read-only in the normal editor.
• Keep portable NBT compatible with existing orbs and item-based quest rewards.
• Add coverage for air, block and entity use, both hands, failed commands, replacement items, and reward-template serialization.
• All 17 Minecraft server integration tests passed.

Upgrade note: orbs created in 0.1.0 remain valid and become single-use after upgrading. A command attempt consumes the orb even if the command fails; malformed sealed NBT does not execute or consume it.

Version numbering has been corrected: the current implementation is 1.0.0, and the original reusable implementation is 0.1.0. Builds previously labelled 1.1.0 and 1.0.0 during development correspond to these versions respectively.
