Configure Everything Claude Code

Run a conversational wizard inside the current harness. Inventory first, collect only supported choices, preview, confirm once, apply non-interactively, verify, and show the welcome only after success. Never clone ECC into a temporary directory or copy plugin components by hand.

For a human-operated terminal, the canonical entry points are ecc setup and npx ecc-universal setup. Inside a harness, use the explicit non-interactive commands below instead.
