Maps ACP session/update notifications to AgentRuntime callbacks using the authoritative SDK 0.24.0 vocabulary: agent_message_chunk->onText, agent_thought_chunk->onThinking, tool_call->onToolStart, tool_call_update (completed/failed)->onToolEnd correlated by toolCallId, plan as full replacement. tool-mapping.ts derives display names + normalizes args. createSession now passes a bridging client handler into connect() so streamed updates reach the engine callbacks. +24 tests (77 total).
