Hey Jake Bailey (@jakebailey), I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/164532/artifacts?artifactName=tgz&fileId=878483ACBB3ADF254CED52B3B2040E424AF942FC5EA4126C9A5FE68FE33F4ADC02&fileName=/typescript-5.8.0-insiders.20250113.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/pr-build@5.8.0-pr-60921-3".;
