"effect": patch

Tighten colliding bounds in place when exporting JSON Schema, instead of moving them into allOf. This applies to numeric, length, item-count and property-count bounds, and an inclusive or exclusive bound implied by the other on the same side is dropped. For example, Schema.Natural now exports minimum: 0, and Schema.Int.check(Schema.isGreaterThan(0)) exports exclusiveMinimum: 0 without the safe-integer minimum.
