Read hotpath Cloud performance verdicts with the `hotpath cloud` CLI and fix Rust performance regressions. Fetches the benchmark report of a commit or pull request, compares it with its baseline under the repository's regression policy and performance budgets, and lists what regressed and which budgets broke, as JSON. Use when the user wants to check a pull request's performance, wait for a CI benchmark, investigate a hotpath.rs PR comment, fix a performance regression or a broken budget, or validate a hotpath policy file.
