fix: carry weather and fire freshness into tool answers

get_weather dropped the proxy's stale status and get_active_fires dropped
FIRMS staleness and failed satellite sources, so answers and the HUD caption
read them as current. Both now report them, and the caption context marks
such sections stale or degraded.
