Automatic TOU schedule

This plan is connected to CalcuRiver’s v0.5.3 usage-time engine. A date/time or recurring charging window can be resolved through America/Los_Angeles into the verified season, weekday/weekend/holiday rule and versioned tariff period. Schedule status: partial date coverage. EV charging windows are split across all applicable TOU periods and returned with an inspectable weighted-rate breakdown.
