0.1.0-beta.1

New beta release; bugs may remain.

• Added self-only start, report, finish and cancel commands.
• Added item-ID net-change accounting, paginated results and default stack-size equivalents.
• Added bounded per-player baselines saved in the world, including restart and death continuity.
• No inventory transfers, restoration, background polling, or external connections.

Validation: all three targets built successfully. Each passed 40,937 core accounting/persistence assertions plus an installed-server production-only boot, 24 runtime assertions, and 25 assertions after a real graceful server restart using the exact release JAR. Metadata, attribution, bytecode target and QA exclusion audited. Graphical client testing has not been performed. Cross-mod compatibility testing is tracked separately by the batch.
