fix: emit #/$defs/ refs in set_tasks schema

TypeBox Type.Cyclic generates bare local refs ("AddTask") which strict
moonshot-flavored JSON Schema gateways (Console Go upstream) reject with
HTTP 400. Rewrite all local $ref values to the #/$defs/ form after
building the schema, and add a regression test asserting the ref format.

Bump version to 0.2.2.
