gsxdsm b6efd89ae5 FN-9097: add Cursor CLI execution runtime

Add a supervised Cursor CLI runtime for routed Cursor model sessions.

- Stream Cursor prompt output into Fusion session callbacks with resume support.
- Support Windows Cursor shims, inactivity-based supervision, and cursor-agent to cursor fallback execution.
- Route Cursor CLI models through the bundled plugin and document the runtime contract.
