a Homebrew tap, so installing does not need a Go toolchain

v0.1.0 does attach binaries for linux and darwin on amd64 and arm64, plus `checksums.txt`, so the release side of #5 already works. What is missing is that the README still only documents `go install`, so a reader has no idea the binaries exist and still concludes they need a Go toolchain. A self-maintained tap closes that and needs no popularity threshold at all: ```sh brew install baryodev/tap/baryovm ``` Only the unprefixed `homebrew/core` name is gated, and that bar is high for a self-submitting owner, so it is not worth aiming at yet. **Scope** - a `brews` block in `.goreleaser.yaml` pointing at a `BaryoDev/homebrew-tap` repository - a token with write access to that repository, available to the release workflow - rewrite the README install section in the order a newcomer needs: brew first, direct tarball second, `go install` last **Worth doing properly** - mention `checksums.txt` in the tarball instructions. This is a tool people run with SSH access to their servers, so teaching an unverified download is the wrong habit to start. - keep the tap repository boring. It is generated output; nothing there should be hand-edited.
