Discord enforces a max of 25 subcommands per slash command group.
Wormhole has 50 children on the main group and 39 on wh set, making
hybrid_group impossible.
Fix: wh is now a regular prefix group, with 7 standalone slash commands
registered for the most common user-facing operations:
/wormhole-list, /wormhole-info, /wormhole-discover,
/wormhole-accept, /wormhole-agree, /wormhole-report,
/wormhole-profile
All 4 context menus still work (Report, Bookmark, Delete, Profile).
All 85+ prefix commands still work via [p]wh.
