chore: run eslint over test files and fix surfaced errors

The `lint` script only scanned `src/`, so the jest config block for
`tests/**` in eslint.config.mjs never actually ran. Extend the script to
cover `tests/` and fix the 3 errors it surfaces:

- domHook.js: setter used `return` for control flow, but a setter's return
  value is silently discarded (no-setter-return) -> use if/else
- scroll.test.js: oversized deltaY literal lost precision
  (no-loss-of-precision) -> 1e20, same magnitude
- drop dead `eslint-disable no-param-reassign` directives in domHook.js and
  useScrollTo.tsx (the rule isn't enabled)
