Consolidate project linting into tool scripts.

The new `tools/check-lint` script checks lints across _all_ lintable files - JS (through `eslint`), and Rust (through `clippy` and `cargo check`). It also checks `eslint` against the whole project, not just against what's in the `ui` subdir, which means it now catches lintable issues in various JS config files.

This was originally part of [another proposal][pr-6]. I've broken it out to make the intent clearer, and to make the proposal easier to get a handle on in isolation from other, related changes. Thanks to @wlonk for their input on this!

[pr-6]: https://codeberg.org/ojacobson/pilcrow/pulls/6

Merges prop/lint-checks into main.
