Add live config overrides and refactor kits

Introduce runtime-configurable settings and defaults across multiple kits and clean up implementations. Kits (Armorer, Backup, Gladiator, Goblin, IceMage, Puppet, and others) now expose companion-object default constants and read values via override() (SPEEDHG_CUSTOM_SETTINGS) with typed accessors. Activation and tick-time behaviour snapshot these values so mid-round config changes don't produce inconsistent effects. Also includes general refactors: clearer getters, small API/formatting cleanup, improved no-op ability placeholders, and minor behavior protections (e.g. disallow stealing Backup kit).
