Add formula engine: data-driven expression evaluator (Core)
Keystone for the gene system. A Formula compiles a string from a def
(lexer -> recursive-descent parser -> tree of Func<IFormulaContext,float>)
once, then evaluates allocation-free against a variable context.

Supports + - * / %, comparisons, && || !, ternary, the constants
pi/tau/e, and functions abs sign floor ceil round sqrt exp log sin cos
tan min max pow clamp lerp step. Deterministic and side-effect-free so
gene-effect formulas stay pure. Covered by FormulaTests (parsing,
precedence, functions, logic/ternary, variables, errors).

mrgameeng

Cross-platform 2D game engine built on MonoGame 3.8.4 (DesktopGL) and Friflo.Engine.ECS — ECS-first, .NET 8, C#.

Developer documentation (Russian): docs/architecture.md, docs/roadmap.md.

Showcase: the LittleSim game — a god-sim built on this engine (vendored there as the engine/ submodule) that demonstrates every engine feature.
