Code Review
This pull request introduces support for the cursor harness (executing the cursor-agent binary) across the CLI, persona-kit, and runtime packages. It configures the necessary sandbox mount rules, mapping of permission bypass modes to the --force flag, and handles sidecar files like AGENTS.md while hiding CLAUDE.md files. Extensive unit tests have been added to verify both interactive and non-interactive behaviors of the new harness. I have no feedback to provide as there are no review comments to address.

- Around line 61-66: Update the executable probe in the detection flow to spawn
the resolved path returned by findOnPath rather than the bare binary name. When
the resolved path is a Windows .cmd or .bat script, invoke it through ComSpec
while preserving direct execution for other paths, and add a regression test
covering Windows command-script detection.
