feat: emoji-visualized gold + weather entertainment plugins

gold: headline price is now USD per gram (XAU/oz divided by 31.1034768),
ounce + bid/ask as reference, timestamp cleaned of timezone/fraction.
weather: per-WMO-code emoji (day/night-aware clear sky), temp + feels
like, humidity, wind. Both verified live; safe in default plain send mode.
