Rebrand README with the e mark and align content with the redesign

Adds the branded header from the redesign: the Fraunces-rendered green
e tile mark, the evo.fugue.run hero tagline, and a badge row. Adds a
Documentation section (user guide, playground, docs.rs), fixes the
Fugue link to the real repo (alexnodeland/fugue, not the stale
fugue-ppl org), and updates the Development section's fugue-ppl
version references from 0.1.0 to the actual 0.2.0.

+A broad evolutionary-computation library for Rust, with an optional probabilistic-programming bridge to [Fugue](https://github.com/alexnodeland/fugue).
 
 The default flagship algorithms (SimpleGA, CMA-ES, NSGA-II, Island Model, Evolution Strategy, EDA/UMDA, SteadyState) are standalone evolutionary computation: they use Fugue's `Trace` only as an address→value data container for the optional `to_trace`/`from_trace` round-trip, not for inference. The genuine "evolution as Bayesian inference over solution spaces" story — a tempered Sequential Monte Carlo pipeline over Fugue's `Model`/`Handler`/`factor` machinery — lives in the `fugue_integration` module (`EvolutionarySMC`/`EvolutionStep`/`BayesianAdaptiveGA`), demonstrated by `examples/bayesian_evolution.rs`. Reach for that module, not the default algorithms, when you want the PPL-powered inference path (EV-17).
