Detailed Description

The accelerator must distinguish "can't handle this" from "didn't converge".

Both used to surface as a bare None, which made them impossible to tell apart at
the call site or in instrumentation. They mean opposite things:

  NOT_HANDLED  no implementation exists for this config -- Python is the only
               one, so the fallback is mandatory and does real work.
  NO_SOLUTION  the physics ran and did not converge. Measured over 102 such
               candidates, the Python fallback then failed on every one, so that
               fallback is re-deriving "infeasible" at full cost.

Only the second is a candidate for ever being short-circuited. Conflating them
would make that change unsafe, because skipping the fallback on NOT_HANDLED would
silently drop every config the accelerator doesn't cover.

The public evaluate/solve/chamber_solve keep the plain-None contract; these tests
also pin that, since every caller keys on `is None`.
