Function character_power

pub fn character_power(
    config: &GameConfig,
    lookups: &ContentLookups,
    level: i64,
    inventory: &[Item],
    abilities: &EquippedAbilities,
    pets: &[Pet],
) -> Result<i64, String>

Character power over the items+pets subset (marginal gear-compare path and arena-bot power): composed attrs → power_from_attrs → honest ability multipliers (ability_power_mults, DPS/EHP-split).

Accumulation order is load-bearing (per-key float sums): char-level attributes, then inventory items (each item’s attributes in order), then pets (in the given slice order, each pet’s stats in order).
