Ufuk approved adding MOTOR's macOS VMs as a runon target (2026-10-26).

• parse_demand accepts "macos" and sets Platform::Macos (cortexkit-exec-remote-types 0.2.14, already pinned). The VM is fixed at 4 vCPUs and offline, so "macos,Nc", "macos,net" and any other option are refused by name before dispatch.
• The bash tool's runon description names the option in one clause, and the general runon guidance says a build or test that needs only macOS (its sandbox, code signing or file watching) can use runon: "macos" instead of running locally; service managers, permission prompts and GUI work stay local.
• Schema artifacts, the catalog fixture and digests, and both plugins' guidance tests are regenerated.
