ooaaooaa123 b861eef26f fix(mcp): address PR review feedback on stability and config ...

Stability fixes in mcp_client.py:
- Fix stderr buffer overflow: start daemon thread to continuously drain
  stderr pipe, preventing 64KB buffer fill that blocks child process
- Fix notification interference: loop readline and skip JSON-RPC messages
  without 'id' field (notifications) instead of treating them as responses
- Fix concurrent race condition: wrap send+receive in _call_lock so
  multiple sessions cannot interleave reads/writes on the same client
- Fix missing timeout: use select.select() with 30s timeout in
  _readline_with_timeout() to prevent infinite block on dead MCP server

Config improvements in tool_manager.py:
- Add _normalize_mcp_configs() to support both list format (mcp_servers)
  and dict format (mcpServers used by Claude Desktop / Cursor)
- Add _load_mcp_configs() to load from ~/cow/mcp.json first, falling back
  to config.json mcp_servers field for backward compatibility
