/* Blanket impl: any `(Prev, P)` where both implement `Phase` is itself a `Phase`.

Combined with the `()` no-op impl, this covers all nested tuple arities:
- `((), P1)` — single phase
- `(((), P1), P2)` — two phases
- `((((), P1), P2), P3)` — three phases, etc.

Built by `SolverFactoryBuilder::with_phase()` which wraps `(self.phases, phase)`.
