5e5b0dbb8f FN-9098: bridge scoped Fusion tools into Cursor
Publish engine-owned Fusion tools to Cursor through a crash-safe, worktree-scoped MCP bridge.

- preserve operator MCP configuration with locking, journaling, quarantine, and lease reconciliation
- enforce identity-scoped fn_* provenance so injected custom and MCP tools are never exposed
- secure loopback dispatch with per-session tokens, heartbeats, cleanup, and normalized tool events
- document the Cursor contract and cover bridge lifecycle, config hygiene, and failure handling

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.
