## Upstream Issue Fix
### Placing a chest next to a claimed double chest breaks the double chest (`#2606`)
**Before:** Placing a single chest outside a claim adjacent to a double chest fully inside the claim would forcibly split the double chest into two singles — even though no cross-claim double chest was actually formed.
**After:** The double chest is left untouched when the placed chest remains single.
The root cause was in `denyConnectingDoubleChestsAcrossClaimBoundary`: it assumed any chest placed near a double chest had connected to it, and unconditionally split both blocks. The fix adds a guard that checks the placed chest's type after placement — if it is still `Chest.Type.SINGLE`, the method returns early and the neighboring double chest is preserved.
