Engine pointer -> 10898b0, which brings in two engine changes:
- the gene-system formula engine (Core): a data-driven expression
evaluator that compiles a def string once and evaluates it
allocation-free against a variable context;
- a parallel refactor splitting the platform out of Core into a new
MrGameEng.Host library.
Game migration for the Host split: reference MrGameEng.Host (+ add it
and its test project to the solution), import MrGameEng.Host where
GameHost/GameHostOptions/Input are used, switch Transition.Fade ->
Transitions.Fade, and read the device via context.GetGraphicsDevice()
now that EngineContext is platform-free.
Showcase the formula engine with a dev-console 'formula <expr>' command
that compiles and evaluates an expression. Also adds docs/гены.md, the
gene-system design doc (phases G1-G5).
