Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
ES and TypeScript modules are strict by default and don’t need this
directive.  ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

Prettier would do this anyway, but it’s separated out for a more
reviewable diff.  Generated by ESLint.

Tim Abbott bdb3da4504 eslint: Add key-spacing linter rule.
Apparently, we didn't have one of these, and thus had a moderate
number of generally very old violations in the codebase.  Fix this and
clear the ones that exist..
