refactor(robo/logger): browser compatibility & package module

[Pkmmte]

Our handy logger has good potential in browsers. It looks good and I've tested that it works, but it did require various changes which I don't feel comfortable pushing because it affects Node compatibility.

We should gracefully do the following:

• Avoid env.js import in browser environments (browsers don't like loadEnv() and its node: imports.
• Write to console instead of process.stdout. Browsers also don't like our node:utils import for inspect, so we may need to selectively import that as well.
• Don't flush logs in browser environments because console is synchronous.
• Refactor color.js to selectively import node:tty outside of browser environments.

Once that's done, we should export the logger as it's own module for better bundle size: @roboplay/robo.js/logger
