• Smart discharge power pacing: discharge rate is calculated to reach min_soc at the end of the window, recalculated every 5 minutes — mirrors smart charge behaviour. House load assists discharge (subtracted from required power). User-specified power acts as a ceiling; pacing still operates below it. Requires battery_capacity_kwh in options; falls back to max power without it.
• Feed-in aware discharge pacing: when feedin_energy_limit_kwh is set, pacing caps the target energy so the export budget is spread across the full window — prevents the session from exhausting the feed-in limit early and stopping before min_soc is reached
• Higher-precision energy calculations: use ResidualEnergy (direct kWh from inverter) instead of integer SoC% × capacity for smart charge/discharge power pacing and deferred start timing — falls back to SoC-based calculation when unavailable
• Session identity tokens: callbacks verify they belong to the current session before taking action — prevents stale timers from destroying replacement sessions
• Fix race conditions: move smart session cancellation before any awaits in force_charge, force_discharge, clear_overrides, and smart_charge handlers — prevents old callbacks from racing with schedule changes
• Rename "Smart Charge Headroom" to Smart Headroom — now applies to both smart charge and smart discharge
• Smart discharge sessions persist pacing state and recalculate power on recovery
