* fix(verifier): don't crash on throwing JS predicates

formulaThunk used to panic whenever goja returned an error from a
predicate callable, and nothing on the LTL -> runner path recovered, so
a malformed spec (e.g. a property whose body throws or touches an
undefined field) would kill the verifier process.

Latch the first error on formulaState, return false so LTL marks the
property violated, and expose PredicateError(name) that walks the
property's formula-spec tree and surfaces the latched cause.

* fix(runner): log predicate errors alongside violations

For each violated property, surface the verifier's latched predicate
error via logger.Warn so operators can distinguish a genuine false
verdict from a malformed spec. Add a runner-level test asserting that a
throwing predicate no longer crashes the run and that the error message
appears in the log.
