* separation and functor for sublanguages

* add coq experiment for termination

* fix tests with envelopes

* add timestamp and print responses to server on terminal

* remove coq experiment for trivial cases and rework gate

* refactor nesting with let*

* remove non-envelope sublang support and tests on server

* manip_err duplication purge and better format as s-expr

* abstract storage with dispatch for sublanguages

* dead code and minor refactor due to old non-envelope parsing on subl
