wip: refactor(sat): generate detailed proofs again 
because proofs now require hypotheses but not in a resolution order, we
can still do conflict minimization.

feat(core): change the way proofs work 
Now a proof returns a `step_id` which identifies its resulting clause.
This might be a dummy value when proofs are disabled.

We attach a step_id to each new clause to make sure it's properly
tracked, but step_ids might outlive their clause (and the actual proof
data might be on disk, only keeping in ram a small unique identifier).

refactor: remove history in conflict resolution; remove simpls 
no need to simplify reasons anymore, we rely on DRUP for that.

refactor: eager proofs; stronger preprocessing 
proofs are now directly emitted (almost) everywhere, which simplifies
a lot of things. preprocessing is more recursive (a bit too much
really).
