e260a72447 sim: log the interaction about to be executed with INFO
I think this is useful to see, without having to drop down to DEBUG
and seeing all the other stuff.

8ec7e616b4 simulator: switch to tracing, run io.run_once and add update queries
* Without tracing crate we cannot log anything that happens in
limbo_core
* IO never ran in step loop inside simulator.
* Added update queries (which currently loop forever for some reason I'm
debugging).

0d0906dce4 Merge 'simulator: implement --load and --watch flags' from Alperen Keleş
The current status of the PR is halfway. The new framing of simulation
runner where `setup_simulation` is separated from `run_simulation`
allows for injecting custom plans easily. The PR is currently missing
the functionality to update the `SimulatorEnv` ad hoc from the plan, as
the environment tables were typically created during the planning phase.
The next steps will be to implement a function `fn
mk_env(InteractionPlan, SimulatorEnv) -> SimulatorEnv`, add `--load`
flag to the CLI for loading a serialized plan file, making a
corresponding environment and running the simulation.
We can optionally combine this with a `--save` option, in which we keep
a seed-vault as part of limbo simulator, corresponding each seed with
its generated plan and save the time to regenerate existing seeds by
just loading them into memory. I am curious to hear thoughts on this?
Would the maintainers be open to adding such a seed-vault? Do you think
the saved time would be worth the complexity of the approach?

Closes #720

- add `--watch` flag
- start saving seeds in persistent storage
- make a separate version of execution functions that use `vector of interaction` instead of `InteractionPlan`

191b586f05 this commit restructures the interaction generation in order to have
better counterexample minimization.

- it separates interaction plans from their state of execution
- it removes closures from the property definitions, encoding properties as an enum variant, and deriving the closures from the variants.
- it adds some naive counterexample minimization capabilities to the Limbo simulator and reduces the plan sizes considerably.
- it makes small changes to various points of the simulator for better error reporting, enhancing code readability, small fixes to handle previously missed cases
