Integrate runtime detection

Describe the feature

I've created detect-runtime a few months ago as a way to detect the current JavaScript runtime where the code is running. As Atinux suggested, we could bring this feature to std-env, which could be a great fit.

detect-runtime follows the WinterCG Runtime Keys specification, which sometimes duplicate the same underlying JavaScript runtime (edge-light is technically workerd, netlify is technically deno). Do we also want to follow this specification, or instead use a subset? (node, deno, bun, workerd, lagon, fastly)

Thanks for creating the issue. I think it is a brilliant idea to add flags to detect runtime environments as well.

Currently, we detect "platforms" mainly for CI environments. We can extend it for runtimes as well from here using a new Array.

I think platform names following runtime key consistency makes the most sense as platforms usually have specific setup and behavior.

We shall also export more flags (from flags.ts) for isNode, isBun, isDeno, etc indicating actual runtime.

Feel free to draft a PR 💯
