pi-schema: opt-in coercion, compile(schema, { coerce: true }) with coerce() and
parse(), the superset of TypeBox's Value.Convert rules and pi-ai's old coercion;
unresolvedRefs option; url and json-pointer-uri-fragment formats.
pi-ai: Tool takes any JSON Schema; validation through pi-schema; Type, Static
and TSchema are no longer exported (breaking). pi-agent-core and pi-durable:
tools on pi-schema, no TypeBox dependency. Coding agent: extensions keep Type,
Static, TSchema and StringEnum through an extension view of pi-ai; built-in
tools stay on TypeBox.
GenerationHooks.afterRun asks, after a run answered, for durable tasks
(runEndTask(task, input)). The answer commits and the run's inputs settle
done first; the generation then creates the tasks as its children in a
finish phase and waits for them in drain, keeping pi.live.run (run.afterRun)
and the conversation busy, so idle waits include them, Stop aborts them and
a crash resumes them. Queued input is placed when they are terminal.
pi.live.run.first and runFailure.first name where a run's history starts,
also for a continue after a failure.
