Expand language palette: add Prolog, Haskell, Zig, fill in Octave

Hub now lists Julia, Octave, Fortran, R, Solidity, Haskell, Prolog,
Zig. Per sub-spec placement:
- Prolog: M3b (logic-based behavioral rules), M3f (consensus logic)
- Haskell: M3a, M3b, M3c, M3e, M3f (type-safe pure math)
- Zig: M3d, M3g (memory-safe performance, replaces C++)
- Octave: filled in where missing (M3b, M3d, M3f, M3g)
