Scaffold

Set up a project for agentic development — either by scaffolding a new monorepo or by onboarding/converging an existing project. Both paths produce a project with OpenSpec, a workspace setup hook, and the canonical BDD e2e-test skill. The existing-project path is an idempotent audit → confirm → converge that also repairs drift on re-run.

Mode Selection

Detect whether this is a new or existing project:

# Check for existing project markers
ls package.json pyproject.toml Cargo.toml go.mod 2>/dev/null

• New project — empty or near-empty directory, no project config files → New Project Flow (Phase 1-8)
• Existing project — has source code and config files → Existing Project Flow — audit → confirm → converge (Phase 0E-6E)
