feat: construct model from congruence closure after th-combination
...
we already obtain a model from theories, and saturate the congruence
closure with it, it's a shame not to use it.

refactor(smt): preprocessing is now using a queue of delayed actions
...
- preprocessing doesn't simplify anymore, it assumes terms are already
simplified. It only adds clauses/adds literals, it does not return
new terms.
- adding clauses/literals to SAT is done as delayed actions, to avoid
issues of reentrancy.
These actions are performed after preprocessing, in a loop that has
access to the SAT solver.

congruence closure (for example in LRA, terms that were preprocessed
away).

feat: proper proof production for theory merges in CC

responsible for some equational hypotheses of this horn clause, being true

feat: add push/pop for assumptions; add check_sat_propagation_only
...
this gives the user the possibility of controlling search by mostly
using assumptions (and the underlying assumption stack) as well as
boolean+theory propagation. The result is **not** complete, but can
still help as a beefed-up contextual simplifier.

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).
