* fix(ai/gateway): AI SDK v6 tool loop on non-Anthropic providers (#1782, #1764)
v6's asSchema() rejected the bare { jsonSchema } object and called it as a
function ("schema is not a function"), killing every tool-using agent run on
non-Anthropic providers and skillopt on all providers. Wrap tool inputSchema
with the SDK jsonSchema() helper, and add a pure toModelMessages() boundary
adapter in chat() that converts tool results to the v6 ModelMessage shape
(role:'tool' + typed output:{type:'json'|'error-text',value}, isError dropped,
non-JSON-safe output normalized). toolLoop stays provider-neutral and unchanged.
Both skillopt tool builders (rollout.ts, write-capture.ts) switch to the shared
paramDefToSchema mapper so enum/default/items survive. Tests run the produced
shapes through real generateText + MockLanguageModelV3.
