fix release pipeline: vendored cava source, fftw in CI, runner arch, smoke test
- Vendor cava/cavacore.c + header (MIT, from karlstav/cava) — the FFI build referenced cava/cavacore.c which was never committed, so every CI runner failed at scripts/build-cavacore.sh and no release was possible. - build-cavacore.sh: discover libfftw3.a across Homebrew and Debian/Ubuntu multiarch paths (FFTW_PREFIX override preserved). - release.yml: install fftw before building cavacore; run the boot smoke test from a bunfig-free dir (the embedded runtime reads the CWD bunfig.toml and this repo's preload entry breaks it — 'preload not found'); use macos-15-intel for darwin-x64 (macos-latest is arm64). - Makefile/build.ts: drop the no-op BUN_CONFIG=bunfig.standalone.toml compile dance (Bun never honored it; compile output is config-independent); delete bunfig.standalone.toml.
