Subject: [PATCH 32/44] feature(lock): output dir

Subject: [PATCH 36/44] feat(actor)!: this is a major rewrite

Many things changed:

1. We're not using blocking fs walks for grammar discovery anymore
2. We're running on a single thread now!
3. We're streaming the tasks with parallelization, still, on a single
CPU, which makes sense, we're not spawning thousands of tasks.
4. The cache implementation is now complete and takes into account
changes in parser spec.
5. Far more importantly, the project is far more readable and
understandable.
