Add messages support to runAgent for multi-turn bot conversations (#23395)

- Extend `runAgent` so callers can pass either a one-shot prompt or a
multi-turn messages array (user / assistant text), matching AI SDK’s XOR
shape — for Slack/Discord/Teams bots that need thread history.
- Enforce exactly one of prompt | messages in AgentRunService; map
messages 1:1 to AI SDK ModelMessages in AgentAsyncExecutorService
- Update shared types, GraphQL/SDK inputs, docs (skills-and-agents), and
regenerate metadata clients; existing prompt-only callers stay unchanged
