Pins v1.0.0 and adds terminal-pet to the install and the test block.
The --hex assertion no longer pins the schema version. It was hardcoded to v4 and broke on the v5 bump — the canonical-frame tests in the repo already pin the version on both the Rust and Swift sides, so asserting it from the tap adds no coverage and couples this formula to the schema across repositories.
Verified: brew audit --strict clean, brew install --build-from-source succeeds, brew test passes, all three binaries report 1.0.0.
