The TPTP frontend was not forcing `pi.avoid_skolems=false`, so TPTP
problems could be solved with the default pattern-inference behavior
instead of the intended frontend-specific setting. This change applies
the override directly to the solver used by TPTP runs.
- **What changed**
- After constructing the TPTP solver, the frontend now sets
`pi.avoid_skolems=false` via solver parameters before `check_sat`.
- The override is scoped to the TPTP solver instance instead of mutating
process-global parameter state.
- **Why this shape**
- Keeps the TPTP behavior explicit at the point where the solver is
created.
- Avoids leaking the parameter change into unrelated solver contexts.
- **Code sketch**
```c++
ctx.set_solver_factory(mk_smt_strategic_solver_factory());
params_ref solver_params;
solver_params.set_bool("pi.avoid_skolems", false);
ctx.get_solver()->updt_params(solver_params);
```

Command context provides the infrastructure for executing commands in front-ends such as SMT-LIB 2.0. It is also provides the solver abstraction to plugin solvers in this kind of front-end.
