4.1.0 (2026-04-26)

⚠ BREAKING CHANGES

• a2a: ADCPClient.pending_task_id is now ADCPClient.active_task_id (same for A2AAdapter). The constructor's context_id= kwarg and reset_context() now raise TypeError (was ValueError) on non-A2A protocols — the string value is fine, the operation doesn't apply to MCP.
