CI: run cargo test on push and pull_request

Adds .github/workflows/test.yml — Ubuntu-only test job triggered on push
to main, PRs to main, and manual dispatch. Mirrors the build job's apt
deps (alsa, udev, wayland, vulkan, mold), uses Swatinem/rust-cache for
incremental cargo caching, and runs `cargo test --workspace`.

renzora_shader is excluded for now because of the 9 pre-existing
material-graph test failures noted in 5370748 — gets re-included once
that suite is cleaned up.
