Economy organ spec review: data flow corrections, toolchain decisions, typo fix

- M3 hub: predictions publish continuously to Marketplace via M2 (not trader-queried)
- M3 BoundedPrediction: three quality metrics (confidence, correctness, certainty)
- M5 traders: read predictions from Marketplace, mixed roster (LLM + bots)
- M7 SAE: monitors at Marketplace level (the only trader interface)
- M6 Conductor: clarified as LLM, not rule-based
- M4 wallets: one multi-chain wallet per trader, strictly 1:1
- M1 Marketplace: added query_predictions interface for traders
- M3d/M3e: Fortran 2018, gfortran, fpm, OpenBLAS, hand-rolled numerics
- M3b typo: "literao" -> "literal"
- SessionStart hook: added gfortran, fpm, Tcl, ECLiPSe Prolog, Zig, Foundry
- Stub fpm.toml for M3d (mev sims)
