The Tools and Apps tabs' "Edit as JSON" editor sent its draft through the
string-to-declared-type conversion `callTool` applies for the widget form, so
`{"count":"01"}` against a numeric schema left as `{"count":1}` — the editor
showed one payload and the wire carried another.
Both JSON-authoring surfaces now refuse such a draft and name the value to
rewrite. Edit-and-replay already did; this makes the Tools and Apps forms
agree with it, which is the consistency #2171's acceptance asks for.
`coercedArgumentNames` and `coercedArgumentsError` move into core/json so the
two surfaces share one predicate and one sentence — the check runs the real
conversion and compares rather than restating its rules, so it cannot drift
from what would actually be sent. Enforcement is opt-in
(`SchemaFormProps.enforceToolArgumentTypes`): an elicitation renders through
the same form and its values are never converted, so enforcing there would
refuse a draft for a reason that is not true of it.
