- Added Tool.coerceArguments (default true); false skips every LLM-quirk
repair pass (object->string stringification, unrecognized-key deletion,
JSON-string parsing) so validation runs verbatim.
- YieldTool opts out: its args are the deliverable, and the repair layer
silently stringified object payloads into string-typed schema fields
while bypassing yield's own validate-and-retry loop.
- Losslessly salvaged weak-caller envelopes observed in session traces:
type:"result" without the result wrapper finalizes as last-turn,
top-level data/error are wrapped, and JSON-string result/data parse
before consuming a schema retry.
