 * Each register() call creates its own closure with its own sessionId, which
 * naturally isolates sessions. The WorkspaceRouter acts as a safety net for
 * after_tool_call events where OpenClaw may deliver the event to the wrong
 * closure (e.g. tool calls interleaving across agents). It resolves the correct
 * sessionId from workspace paths in tool params, falling back to the closure
 * sessionId when no workspace is detected.
