Automation and Castrel Proxy Upgrades

Automation and Castrel Proxy Upgrades
This release focuses on two core capability areas: automation and Castrel Proxy. Automation now delivers a stronger scheduled-execution and notification loop, while Castrel Proxy adds a new proxy mode for private-network access.

New Feature: Automation

This release turns automation into a more reliable operational loop across scheduling, notification delivery, and follow-up conversation flows. Compared with earlier versions, this iteration fixes notification-channel behavior, mention handling, and execution stability issues that previously caused duplicate notices or unreliable task persistence.

Automation details: Automations.

This release also improves the event configuration flow inside automation. You can define clearer trigger conditions and execution rules, so automation can run with both schedule-driven and event-driven patterns in production operations.

Proxy: New Proxy Mode

Castrel Proxy adds a new proxy mode and further strengthens private-network observability access in this release. Permission controls were also hardened across MCP, skills, command execution, and filesystem access so teams can apply least-privilege controls in production.
