Instead of `.cjs`; enough with this nonsense.

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)

- 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.

This fixes the directory target rule problem.

Thanks to Rudi Grinberg!!

This should cleanup the root directory a bit; I've placed the cli
files inside `frontend`, but quite a few of these files should
eventually move to backend, as it seems to me that they functionality
that the "server" should provide, but we can do like this for now and
move things to `backend` as we see fit.

In @wacoq alias.

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...

We move vendored things to `vendor` and let dune know about it.
We bump serapi dep to the head of the v8.16 branch.

We also adjust build deps a bit better, in particular to avoid Dune
3.4 which is buggy for us.

Beware this will require `git submodule update` on the work tree.

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.

Build order fluctuations caused errors in our CI because of deps
not being built when needed, specifically for Ltac2.

It must be explicated as a dependency otherwise Dune will *delete*
it on the first occasion. My hack with using an alias thus failed
spectacularly.

Until this is changed in Coq, apply this patch copied from master.

Since the `directory-targets` plugin is not quite ready, rule for
`node_modules` is converted into an alias. It doesn't really matter,
in this particular case.

Also generated symbols for the examples.

It is no longer in use. Serving from source dir still works with `make links`,
but you must run `make links-clean` before building with Dune again.

- 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.

Consolidated Webpack config in a single file, as is more common for
Webpack.
Provided npm scripts for running it as usual.

And so it begins.

This is phrased as an "addon"; I think that not only libraries can be
"addons" but this kind of interop UI functionality should be as well.

It does not mean that UI addons should be built outside of the jsCoq
source tree like mathcomp & co.
If they are small enough, they are ok where they are in `ui-js/addon`.

This has some minor advantages, including dune handling of arguments.

Nothing too remarkable, code-wise, but a big change upstream is the
addition of `zarith` as a hard dependency.

TODO:

- update addons

What was needed in order to run unit tests in Node.js is
now located in `headless.ts`.
It is invoked via the regular CLI (bundled with Webpack).

Fixes #195.

Coq 8.12 has multi-char bullets (e.g. `--` or `***`).

When building chunked packages using the CLI.

Brought over from v8.11+wacoq.

Ported old code to TypeScript with major rearrangement.
Build based on Webpack.

This is a workaround for #171 until we have something better.
