icu-minify vulnerabilities

mcp-data-vis vulnerable to denial of service via unsanitized `select` key lookup on `Object.prototype` with `precompile: true`

## Summary `icu-minify`'s runtime formatter resolves `select` branches by looking up the runtime value as a plain property on a prototype-bearing object. When the value coerces to a key that exists on `Object.prototype` (e.g. `toString`, `__proto__`, `constructor`, `hasOwnProperty`, `valueOf`), the lookup returns a truthy value that short-circuits the `?? options.other` fallback, and the downstream iterator crashes with `TypeError: nodes is not iterable`. Any consumer that forwards user input into a `{arg, select, …}` placeholder — a common idiom for `role`, `status`, `type`, `gender` — can be crashed per-request by supplying one of those ke
