Bug Description | 问题描述

The memory_search tool uses hardcoded owner="agent:main" when no explicit owner parameter is provided.

This breaks the documented multi-agent isolation: "检索时自动过滤为当前 Agent + public"

Expected: Auto-detect agentId from ctx.workspaceDir or hookCtx.agentId

Workaround: Extract agentId from workspaceDir path (workspace-dev → agent:dev)

How to Reproduce | 如何重现

1. Set up multiple agents (workspace-dev, workspace-javis)
2. Call memory_search without owner parameter
3. Check logs: shows owner=agent:main instead of agent:dev
