yuanyuanxiang 6ba6b0289d Feature: Add list_processes, list_windows and get_activity_history MCP tools
Add three read-only P2b MCP tools over the existing protocol. list_processes and list_windows trigger the client via COMMAND_SYSTEM / COMMAND_WSLIST on the main connection and receive TOKEN_PSLIST / TOKEN_WSLIST on a one-shot sub-link; get_activity_history uses the main-connection RPC COMMAND_QUERY_ACTIVITY -> TOKEN_REPORT_ACTIVITY. A per-host single-flight pending registry (m_Pending) with a 20s timeout correlates each response to its request and rejects a concurrent request for the same host with -32003. Parsers stop on the first empty record to ignore the client's LocalSize trailing zero padding, and window titles are decoded per the client UTF-8 capability bit. MessageHandle only adds if-guarded branches, so the MFC dialogs are untouched. Sync Mcp_Phase2_Design.md with the mode A'/A architecture, the verification notes, and the registry-backed config location.
