Diagnostics
- Added structured logging, performance metrics, hitch capture, and improved log analysis.
- Added secure launcher diagnostic submissions for crashes, lag, rubber-banding, and missing items.
Items and Gold
- Reworked world items with voxel placement, stacking, gravity, compact rendering, collision, and safer pickups.
- Reworked gold into varied-value, center-weighted piles that grow taller for larger amounts.
Vaults
- Made vault items behave like overworld items, with permanent persistence as the main difference.
- Added incremental loading, paged saving, configurable capacity, and multiple isolated vaults per bank server.
Launcher and Testing
- Fixed launcher migration paths, logging options, and optional web exports.
- Added item, gold, vault-load, collision, and multi-account tests.
