• Add GitHub CI coverage across Windows, macOS, and Linux, with a portable cross-platform test suite plus Linux-only full integration/E2E coverage.
• Harden background routing by validating parentThreadId, combining reserved-job and session-routing metadata into one helper, and making background review/rescue explicitly use built-in forwarding subagents rather than direct detached companion processes.
• Stop exposing managed job log paths through user/model-facing status and result surfaces while keeping on-disk logs for debugging.
• Make installed skill-path materialization consistent for both staged installs and direct local-checkout installs, and centralize installer path helpers for reuse.
• Switch sandbox temp-dir settings from a hardcoded /tmp path to the OS temp directory so the runtime configuration stays valid off Linux.
