The previous code attempted to register a maintenance mode gate via
@self.tree.interaction_check inside setup_hook. That pattern is invalid
in discord.py — interaction_check is an overridable method on CommandTree,
not a decorator. The assignment was silently dropped, making maintenance
mode a no-op and producing a RuntimeWarning about an unawaited coroutine.
Changes:
- Add MaintenanceAwareTree(discord.app_commands.CommandTree) that overrides
interaction_check: blocks non-admins when bot.maintenance_mode is True,
always passes admins through, no-op when maintenance mode is off
- Pass tree_cls=MaintenanceAwareTree to super().__init__() in SBABot.__init__
- Add self.maintenance_mode: bool = False to SBABot.__init__
- Update /admin-maintenance command to actually toggle bot.maintenance_mode
- Add tests/test_bot_maintenance_tree.py with 8 unit tests covering all
maintenance mode states, admin pass-through, DM context, and missing attr
