Homebrew 6.0.11 adds a brew vulns command and OSV advisory export

Sources: GitHub release
Summary: Homebrew published 6.0.11 on 2026-07-14, a patch on the 6.0 line. It adds a brew vulns command and tooling to export OSV-format advisories for a Homebrew advisory database, extends cask metadata migration to JSON for all users, and fixes a brew outdated --greedy crash on installed casks without a URL. Performance changes start bottle downloads before dependency fetches and prewarm Bootsnap caches after brew update. No security fixes to Homebrew itself are listed.
Why it matters: Building vulnerability lookup and advisory export into the default macOS and Linux package manager moves dependency scanning closer to the install path.
