v0.6.3

What's changed

• derive an explicit estimated cleaning energy total from X20+ clean-log runtime using the published 75W rated robot power
• surface the estimate across Mission Control history cards plus xiao status --full, xiao report, and xiao device history
• keep the value clearly labeled as an estimate (kWh @ 75W) instead of pretending it is measured device telemetry

Research basis

• Xiaomi's published X20+ specs list Rated Power 75W
• the official xiaomi.vacuum.c102gl clean-log fields still expose aggregate time/count/area only
• adjacent Home Assistant energy tooling reinforces kWh as the user-facing unit for watt-time derived totals
