docs: add semrouter banner image to README

NeuralEmpowerment · NeuralEmpowerment · commit 152c31db1f6d · 2026-05-07T12:20:24.000-07:00
assets/banner.png shows the semantic routing flow visualization
with the project tagline. Linked via absolute GitHub URL so it
renders on both GitHub and crates.io. assets/ added to Cargo.toml
exclude list to keep the published tarball small (1.3MB image
not needed in crate; crates.io fetches it from the absolute URL).
