Adds a `bumpHomebrewTap(version)` step that fetches the freshly published
tarball from registry.npmjs.org, recomputes its sha256, rewrites
homebrew-tap/Formula/fusion.rb (url + sha256), and pushes a follow-up
`chore(tap): bump fusion to vX.Y.Z` commit to main. Includes a short
retry loop because the registry can take a few seconds to surface a
just-published tarball. All failures are warnings — they don't abort
the release since the npm publish + tag are already out.
