(#16761) Thanks @napetrov. - Agents/Thinking defaults: set `adaptive` as the default thinking level for Anthropic Claude 4.6 models (including Bedrock Claude 4.6 refs) while keeping other reasoning-capable models at `low` unless explicitly configured. - Gateway/Container probes: add built-in HTTP liveness/readiness endpoints (`/health`, `/healthz`, `/ready`, `/readyz`) for Docker/Kubernetes health checks, with fallback routing so existing handlers on those paths are not shadowed. (#31272) Thanks @vincentkoc. - Android/Nodes: add `camera.list`, `device.permissions`, `device.health`, and `notifications.actions` (`open`/`dismiss`/`reply`) on Android nodes, plus first-class node-tool actions for the new device/notification commands.
