Custom Worlds

Added

• /cw config worldedit <true|false> - let every player (not just OPs) use WorldEdit commands in a specific dimension, without granting them OP. WorldEdit is creative-only for everyone, OPs included (survival players are refused). Requires WorldEdit to be installed; no build/block limits are enforced, it's an admin-trust decision per world.
• /cw config worldspawn [<pos>] [<angle>] - set a custom spawn point for a custom dimension (used the first time any player arrives with no remembered position). No arguments uses your current position/facing; reset reverts to the automatic safe-spawn search.
• /cw create <name> <type> [seed] [structures] - optional trailing flag to disable structure generation (villages, strongholds, etc.) for a new world. Defaults to true (vanilla behavior) when omitted.

Fixed

• World border no longer leaks between dimensions. Vanilla only gives the overworld its own border; every other dimension (nether, end, and therefore every custom world) shared that same border object by default. Running /cw config worldborder in one custom world was silently rewriting the overworld's border and every other custom world's border at the same time. Every dimension now gets its own independent border.
• Fixed a related, not-yet-reported issue at the same root cause: a custom dimension's spawn point was aliased to the overworld's, so vanilla's own /setworldspawn used inside a custom world would have corrupted the real overworld spawn point.
