Homebrew 7.0.0

Homebrew 7.0.0 introduces faster installations and upgrades through greater concurrency in downloads, preparation, and cleanup, while adding a native macOS app, built-in vulnerability checks, and an advisory database. It strengthens sandboxing, removes macOS 10.15 support, moves Intel Macs to Tier 3, and patches multiple security advisories (e.g., GHSA-rg9r-ppxp-87hm, GHSA-5263-whxq-77hp).
