glenn schrooyenandClaude 97686319f3 TARIFF-24 round 3: a run planned with a forecast keeps its gap to its end
checks / unit (pull_request) Successful in 51m57s
infra-pin / fresh (pull_request) Successful in 1s
Losing the solar forecast mid-run used to widen the gap at once and stop a
grid charge (and a sensor that went unavailable for a minute stopped and
restarted it). A run under way when the forecast is lost now keeps the gap it
was planned with until it ends (Controller.weather_held(), recorded by
_wx_track() each cycle a forecast is read); the wider gap applies from the next
run. The plan key holds the hold state so the plan rebuilds when it ends. Home's
mirror (homeview.trade_verdict) asks the same weather_held(now).

Tests: test_tariff24_weather.py part 4 (going: the charge continues to the run's
end, the next run is not_worth; flap of one and two reads: no stop, no restart;
Home agrees) and a test_modes_p4.py scenario that runs a forecast day at a gap
between 1x and 1.5x the cycle cost. DECISIONS wording follows.

glenn schrooyenandClaude 382b0ea411 TARIFF-24 round 2: a usable solar forecast replaces the "no weather" x1.5 (AUDIT-02 F1)
With battery modes on, the price gap a mode needs was always widened x1.5 by
Uncertainty.NO_WEATHER, even with a solar forecast read, so a 0.08 day/night
gap never traded at the shipped cycle cost. The doubt is now added only when
no usable forecast is read (solar_fc is None, the day plan's own test), in the
run plan (_price_runs), the charge gate (_mode_roles) and Home's mirror
(homeview.trade_verdict). The rule is one helper, arbitrage.weather_uncertainty();
the modes-off trade path (main.py cycle) keeps its literal NO_WEATHER.

DOCS "Battery modes" sentence, CHANGELOG 0.19.1 line and the DECISIONS note
follow. Tests: test_tariff24_weather.py.
