feat: Interrupt for low coded CAS agents [JAR-9208]

[JoshParkSJ]

Changes

• for tool confirmation, defer startToolCall, prompt user interrupt start/end, and then run startToolCall from runtime layer, and endToolCall on tool message
• providing metadata in the tool response for HITL tools because there was a bug where the agent would think it mistakenly called the wrong tool even though the user intentionally modified the arguments (see discussion here)
• detailed thread here for durable_interrupt

nit: maybe consider moving durable_interrupt into another top level module like _utils.
