Store ADK sessions in AgentCore short-term memory using the conversational+blob mapping from the google#6920 PoC, and implement the rest of BaseSessionService (ids, get/list/delete, partial skip). Fixes google#6920

Summary
AgentCoreSessionService, aBaseSessionServicebacked by Amazon Bedrock AgentCore Memory short-term memory, soRunner(session_service=...)can persist ADK sessions there.conversationalpayload (when there is text) plus ablobof the full ADKEventJSON, so STM extraction still works and tool calls / state / metadata round-trip.BaseSessionServicecontract on top of that mapping: generated session ids,AlreadyExistsError,get_sessionreturningNonewhen missing,list_sessions(including all users of an app),delete_sessionviadelete_event, skippartialevents, bootstrap event so empty sessions exist in AgentCore, andactorId = {app_name}:{user_id}so two ADK apps sharing a Memory resource do not collide.Fixes #6920
