feat: Upgrade OpenClaw to 2026.4.11 with full new features

Upgraded from 2026.4.2 to 2026.4.11:

Stability & Transport:
- Safer provider transport with health checks and auto failover
- Connection pooling and graceful degradation

Exec Approvals (enhanced):
- 3-tier classification: auto_approve, require_approval, forbidden
- 11 approval-gated actions, 6 auto-approved, 3 forbidden

Subagents:
- max_spawn_depth: 2 (orchestrator pattern)
- max_concurrent: 8 with session isolation

Channels:
- WhatsApp: emoji reactions, typing indicator, auto-chunking
- Slack: exec approval routing
- Matrix: streaming + proxy + history + thread replies
- Email: outbound primary

Memory:
- Active Memory plugin with auto context injection
- REM backfill (replay old notes into durable memory)

Flows:
- Background task flow control plane (SQLite-backed)
- Checkpoint on step, resume on restart
