jgrusewski b664673df3 feat(surfer): Fear&Greed gate — sentiment regime-dependent, not robust ...

F&G market-timing: full-sample IC negative (fear->continuation), recent OOS positive,
IS/OOS sign-flip (-0.65->+0.75), 2026 flipped -0.8 = regime-dependent, not robust.
Free non-price is mostly market-wide timing (low-breadth, regime-prone); cross-sectional
on-chain (the valuable kind) needs paid data. Non-price free frontier mostly dead.
