v0.54.0

⚠ BREAKING CHANGES

• VacuumEntityFeature.BATTERY, VacuumAttributes.battery_icon, VacuumAttributes.battery_level, and VacuumAttributes.supports_battery have been removed, mirroring their removal from Home Assistant core's base vacuum entity in 2026.9.0. Code reading vacuum battery state directly from these fields must switch to the entity's own battery sensor (e.g. a paired sensor.*_battery entity), which is how HA core itself now exposes this data.
