A new unified command architecture consolidates claim-related commands under `/claim` for players and `/aclaim` for administrators. The unified command system uses a separate `alias.yml` file that is auto-generated with defaults on first run.
New `/checkclaimexpiry [player]` command provides detailed expiration information.
Various claiming/investigation interaction & visualization improvements.
Fixed a bug where subdivisions couldn't be created on same x/z boundary of parent claims.
