Propagate graceful-suspend signals through detached run contexts and let
only opt-in suspendable tools re-attach cancellation, so AsTool sub-agents
can checkpoint and restore across nested trees while leaf tools keep
running detached.
Add focused agent and worker tests for single and multi-level suspend/
restore flows, plus heartbeat lease-loss and nested-restore error paths to
harden functional behavior under failure conditions.

Introduce Checkpoint, CheckpointStore, SuspendedError, AgentRegistry,
and CompletedCall types. Add cooperative stop signal via context.
Export CompletedCall (was unexported completedCall) so checkpoints
can reference completed tool results. Add JSON tags to ToolResult
and ApprovalResult for checkpoint serialization.

jsonSchemaFor panicked on unsupported types, which meant
FunctionTool, NewOutputType, and RunTyped would crash the
process during setup rather than returning a normal error.
