* fix: add context prompt to sleeptime agent user message
Previously the sleeptime agent received only the raw conversation
transcript with no context, causing identity confusion where the
agent would believe it was the primary agent.
Now includes a pre-prompt that:
- Uses "sleeptime agent" terminology explicitly
- Clarifies the agent is NOT the primary agent
- Explains message labels (assistant = primary agent)
- States the agent has no prior turns in the transcript
- Describes the memory management role
