refactor(scripts): overhaul

[uncenter]

Often feels like an uphill battle trying to wrangle our scripts here. This PR aims to refactor and reorganize the scripts side of the codebase to a more understandable, readable point.

Goals/thoughts:

• Prefer importing * as xyz instead of specific functions if said functions are vague - examples of this include @std/path and @std/yaml.
• Prefer await over .then. Often the code here gets mangled into super nested and chained tangles "on a single line", .then is a big part of this issue.
• Sort imports semantically. This might be more opinionated but I have found that putting constants and type imports at the top of the file, with a line of separation between those and the more use(d, ful) functions is helpful when reading through to parse what is being imported.
• Root level functions should use the function keyword declaration syntax rather than the arrow function syntax. I find this makes code more readable as you can more easily locate functions and distinguish them from actual variables/constants.
• WETT should be one of the larger principles at work here: write everything three times. If we are repeating code 3+ times, abstract it into a function to make updates to that logic easier across the whole catalog of scripts!
• As part of the last one, I've moved the utilities into a new utils/ folder, rather than the previous clump in utils.ts.
