For politics/tech/events markets there is no above/below price notion, so
is_price_above defaulted to False (or flipped on accidental wording like
"reach") and sign-inverted the macro adjustments: BTC +5% or high Fear&Greed
subtracted probability from YES on "Will X win the election?" markets.
Skip both signals entirely for non-price markets: contributions stay 0.0,
feat_mom_lo / feat_fg_lo persist as 0.0. Price markets (BTC/ETH/crypto)
keep the exact current behavior, including the below-market sign flip.
Removes the now-dead BTC(sentiment) momentum branch and its 0.5 attenuator.
