fix: hoist $defs to the schema root for set_tasks

Refs like "#/$defs/AddTask" resolve from the document root, but
Type.Cyclic nested the $defs inside tasks.items, so the moonshot-flavored
gateway reported "$defs not found for reference". Hoist all $defs entries
to the parameter schema root and strip the synthetic $id that would change
fragment resolution. Update the regression test to pin the layout.

Bump version to 0.2.3.
