feat(openclaw): support /hooks/agent endpoint and multi-endpoint detection

Add OpenClawEndpointKind type to distinguish between /hooks/wake,
/hooks/agent, open_responses, and generic endpoints. Build appropriate
payloads per endpoint kind with optional sessionKey inclusion.
Refactor webhook execution to use endpoint-aware payload construction.
