Tighten broadcast formats to fit 140 chars with critical info preserved:
traffic (directions/milepost never abbreviated, narrative trimmed from
end), nws hazard wording tightened (towns already path-sampled), fires
(drop ID line + ** + discovery time), avy (advice -> first sentence),
satpass/quake safety cap. Fire digest broadcast disabled by default.
All budget-aware via the shared max_chars.
