This is more modular and provides a workflow speedup in many cases.

We also add a couple of bugfixes (tsconfig.json missing from dune
deps, missing await in esbuild.mjs)

These are the current numbers on release:

```
 261K -- dist/wacoq_worker.js
 369K -- dist/frontend/index.css
 583K -- dist/frontend/index.js
```

- don't rebuild the cli stuff when the frontend/backend changes
- make tests work again

Seems to work! I guess it can be done better, but for now that is OK.

This is not perfect but it works (and it is much faster).

For some reason I couldn't make `fflate-unzip` work with ESBuild, so
I've placed a copy and tweaked the exports.

This is a large build-time improvement, moreover we can get rid of a
lot of troublesome code regarding how to manage assets.

`esbuild` has proven a great tool so far.

Tested with both backends.

We still keep the CLI and the WASM backend on webpack, the idea is
to move them to esbuild in subsequent commits.

CLI should use a native Coq instead, it is super-slow.

We also disabled the `collab` and `ide-project` builds for now,
re-adding before merging hopefully.

The compatibility story with user .html pages needs to be revised,
IMHO as this is a foundation for the LSP backend this is the time to
drop support for some patterns we had in the past.

All wasm binaries are read from `node_modules` directly, so there is no
need for a `bin/` directory (this was a hack).

The deps are collected in a meta-package `wacoq-deps`, which is
published to NPM separately and should not change often.

Will gradually move parts from the other repo, wacoq-bin, to `backend/wasm`.
This will allow some code reuse between the backends.

We reorganize jsCoq's source code as to be more modular, in particular
we start to place backend files under the `backend` directoy, and
frontend files under `frontend`.

Code as it now does work, note however that still quite a bit of work
is needed. In particular, the headless frontend should get its own
directory, the coq-jslib directory should go away, use more types,
etc...

Newer webpack{,-cli} support this.

In princple, should change Ronin to not rely on the literal name
of the constructor.

The bundle (`.bundle.min.js`) is now needed for the menu.

This requires renaming of webpack.config.js to indicate it is a
CommonJS module system.

We do some extra fixes for the webpack build to work.

Well not quite, the `dsp` dependency needs to be resolved.

MathJax added as an NPM dependency instead of using CDN.
(Because same-origin policy stuff.)

Completely bare-bones, no UI yet.
Required quite a lot of the usual polyfills.

Sync `package.json.wacoq` with `package.json`.

As suggested by @hannelita.

Allows multiple jobs to invoke the SDK in parallel. If the SDK is not installed,
the first to lock the file will carry out the install.

Currently separate from the main cli, but for no good reason.
Should be a sub-command.

+ updated Mocha (npm audit stuff).

- Migrated patches for 8.14.
- Up wacoq to 8.14 in docker image
- install: 8.14 requires `coq-core` and `coq-stdlib` to be installed.
- Set version 0.14.0.

Quote escaping hell in this tiny `sed` script.

Previous package, `vue-context`, is abandoned.
