VectorVein now includes a headless workflow CLI and a console-mode VectorVeinCLI executable in the Windows, macOS and Linux packages.

Commands cover workspace initialization, workflow validation/creation/export/update/patching, synchronous execution, run status and records. The CLI shares the desktop data model and execution engine, emits UTF-8 JSON, supports isolated workspaces and external model settings, and preserves workflow versions in run records.

Model nodes support explicit output/concurrency limits, fixed-endpoint selection and schema-failure diagnostics. Each request reserves the rate limit once, and cleanup timers no longer delay CLI exit.

Validation: 60 backend tests passed on all three release platforms. Each packaged CLI passed help and workspace-initialization smoke checks. The existing neutral end-to-end report example also passed.

CLI commands and configuration

Implementation: [#112]. Release version: [#113]. The existing v0.4.17 tag remains unchanged.
