No Cooldowns

Evidence

Ran on Kiln's test stand (2026-11-04): NoCooldowns did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/command/v2/CommandRegistrationCallback; ClientLoginHandler did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/client/networking/v1/ClientPlayConnectionEvents.
