• Add Context.get_option() to access options outside the command callback in a type-safe manner.
• Add Client.walk_commands() and Plugin.walk_commands() to iterate over all commands & subcommands of a given type in a type-safe manner.
• Add CallableCommandProto.display_name, SlashCommand.make_mention(), SlashSubCommand.make_mention().
• Change Context.respond_with_builder() to attempt a followup message when the interaction has an initial response and a message builder was passed.
• Remove the acquire() method from LimiterProto to make it easier to implement custom limiters.
• Split arc.utils.hooks.RateLimiter into arc.utils.RateLimiter and arc.utils.hooks.LimiterHook. This allows arc.utils.RateLimiter to be used independently of an arc context object.
