chore: Apply linting everywhere

As titled.

Almost all this PR does is remove semicolons to match a specific opinionated linting setup.

I'm not keen on any linting/formatting that involves removing semicolons. Without them developers need to be aware of the automatic semicolon rules. This knowledge is not required when semicolons are used.

This PR applies the linting rules already applied across the rest of the project. There's pretty much only two situations where ASI knowledge is needed:

function foo () {}
;(function IIFE () { /* do something */ })()
// ^ need the explicit semicolon

let a = 'foo'
console.log('bar')
;[a] = ['bam']
// I had to rip this from a SO answer because I couldn't even think of a way to induce it.

ASI is a non-issue.

Oh my bad. I misread the diff!
